For example, an absorbent article such as a diaper includes an indicator that is discolored by urine (Patent Document 1). The absorbent article described in Patent Document 1 has a character symbol provided on the outer cover and a plurality of discretely arranged indicator symbols. In Patent Document 1, the character symbol and the indicator symbol are formed by symbols that are related to each other. Thereby, an absorbent article having a high design property can be provided.

Patent No. 4721598

Indicators provided on absorbent articles discolor in response to urine. In such an indicator, the boundary between the portion discolored by urine and the portion not discolored tends to be ambiguous. That is, the color of the indicator changes continuously over a relatively wide area from a urine-rich area to a urine-free area. Therefore, it may be difficult for users such as infants and assistants such as parents to distinguish between areas containing a large amount of urine, areas containing a small amount of urine, and areas not containing urine, depending on the color of the indicator. be.

Therefore, an absorbent article containing an indicator that makes it easy to distinguish between a region containing a large amount of urine, a region containing a small amount of urine, and a region containing no urine is desired.

The absorbent article according to one embodiment includes an indicator symbol including an indicator that is discolored by urine, the indicator symbol includes a high weighing portion and a low weighing portion, and the high weighing portion is the said in the first direction. It is provided on the edge of the indicator symbol.

It is a top view of the absorbent article which concerns on one Embodiment. It is sectional drawing of the absorbent article along line 2A-2A of FIG.

(1) Outline of the Invention The absorbent article according to one embodiment includes an indicator symbol including an indicator that is discolored by urine, the indicator symbol includes a high weighing portion and a low weighing portion, and the high weighing portion includes a high weighing portion. , Is provided on the edge of the indicator symbol in the first direction.

The indicator pattern changes color in response to urine. The highly weighed portion of the indicator material constituting the indicator symbol changes to a different color depending on the concentration of urine. For example, when the concentration of urine is high, the high weighing portion changes to the same color as the low weighing portion. Further, when the concentration of urine is small, the high weighing portion changes to a color different from the color of the low weighing portion. This is because when the concentration of urine is low, a part of the high weighing part does not react with urine.

Therefore, when the concentration of urine is high, the high weighing portion and the low weighing portion change to substantially the same color, so that the indicator symbol changes to a substantially monochromatic symbol different from the original color. Further, when the concentration of urine is small, the high weighing portion and the low weighing portion change to different colors, so that the indicator symbol changes to a symbol containing different colors. In other words, the indicator symbol can change to have a shadow when the concentration of urine is low. As a result, the indicator symbol in the region where the urine concentration is low is easily recognized as a symbol which is seemingly different from the indicator symbol in the region where the urine concentration is high. Here, the concentration of urine is usually highest at the place where urine first adheres and decreases with the diffusion of urine. That is, the higher the urine concentration, the higher the urine volume, and the lower the urine concentration, the lower the urine volume. Therefore, in the indicator symbol of the above aspect, it is easy to distinguish a region containing a large amount of urine, a region containing a small amount of urine, and a region not containing urine depending on the difference in urine concentration.

Further, even when urine is not contained, the high weighing portion and the low weighing portion of the indicator symbol appear to be shaded, so that the design of the indicator symbol can be improved.

According to a preferred embodiment, the high weighing portion is provided only on the edge of the indicator symbol in the first direction.

As a result, a place where the indicator symbol can be shaded is specified at the edge in one direction. Therefore, since it is easy for the user and the assistant to grasp the position of the indicator symbol where the shadow may occur, the user and the assistant can check whether the area contains some urine by looking at the discolored symbol. It will be easier to judge.

Further, since the high weighing portion exists at the edge of the indicator symbol, the high weighing portion can be visually recognized like a shadow and can be recognized as a symbol having a three-dimensional effect. Therefore, the design of the indicator design can be improved.

According to a preferred embodiment, the absorbent article has a front waistline area, an inseam area, and a rear waistline area, and the first direction is before and after connecting the front waistline area and the rear waistline area. In the direction, the high weighing portion is provided on the rear edge of the indicator symbol.

For users who often sleep on their backs, such as infants, urine adhering to the inseam area tends to flow from the inseam area to the dorsal side. Therefore, urine may leak from the dorsal side without noticing that the urine is diffused to the dorsal side. If the high weighing portion is provided on the rear edge of the indicator symbol, the boundary of discoloration of the indicator symbol is likely to occur as the urine volume changes from the inseam region to the dorsal direction. That is, in the posterior waist circumference area where urine is likely to diffuse, a high weighing portion that can be used to distinguish the urine volume is provided on the dorsal side, so that the user or an assistant can use the urine volume at a position closer to the dorsal side. The judgment can be confirmed accurately.

According to a preferred embodiment, the high weighing portion of the indicator symbol provided in the front waist circumference region is provided on either the edge on the inseam region side or the edge on the side opposite to the inseam region. The high weighing portion of the indicator symbol provided in the rear waist circumference region is provided on the other side of the edge on the inseam region side and the edge on the side opposite to the inseam region.

When sleeping on his back, urine adhering to the inseam area tends to flow from the inseam area to the dorsal side. Therefore, even when the amount of urine is large, urine is difficult to diffuse to the ventral side. That is, in the anterior waist circumference area where urine is difficult to diffuse, a high weighing portion that can be used to distinguish the urine volume is provided on the inseam side, so that the user or an assistant needs to judge the urine volume more. The urine volume can be confirmed more accurately on the side.

On the other hand, when sleeping on the prone position, urine adhering to the inseam area tends to flow from the inseam area to the ventral side. Therefore, even when the amount of urine is large, urine is difficult to diffuse to the dorsal side. That is, in the posterior waist circumference area where urine is difficult to diffuse, a high weighing portion that can be used to distinguish the urine volume is provided on the inseam side, so that the user or an assistant needs to judge the urine volume more. The urine volume can be confirmed more accurately on the side.

According to a preferred embodiment, in the indicator symbol provided in the front waist circumference region, the high weighing portion is provided on the edge on the inseam region side, and in the indicator symbol provided in the rear waist circumference region. , The high weighing portion is provided on the edge opposite to the inseam area.

For users who often sleep on their backs, such as infants, urine adhering to the inseam area tends to flow from the inseam area to the dorsal side. Therefore, even when the amount of urine is large, urine is difficult to diffuse to the ventral side. That is, in the anterior waist circumference area where urine is difficult to diffuse, a high weighing portion that can be used to distinguish the urine volume is provided on the inseam side, so that the user or an assistant needs to judge the urine volume more. The urine volume can be confirmed more accurately on the side.

According to a preferred embodiment, a plurality of the indicator symbols are provided, and the high weighing portion of the indicator symbol is provided on the same side edge of each of the indicator symbols.

As a result, since the locations where shadows can occur in the plurality of indicator symbols are the same, it becomes easier for the user and the assistant to grasp the position where the shadows can occur in the indicator symbols. Therefore, it becomes easier for the user and the assistant to determine whether or not the area contains some urine by looking at the discolored pattern.

Further, since the plurality of indicator symbols have a unified atmosphere, the design of the absorbent article as a whole is improved.

According to a preferred embodiment, the indicator symbol includes a region surrounded by a region including the indicator and not including the indicator, and the high weighing unit displays the indicator in the first direction. It is provided on the edge of the area not included.

Since the high weighing portion exists at the edge of the region not including the indicator in the first direction, the high weighing portion can be visually recognized as a shadow of the symbol and can be recognized as a more three-dimensional symbol. .. Therefore, the design of the indicator design can be further improved.

According to a preferred embodiment, the length of the high weighing portion in the first direction is constant.

As a result, the high weighing portion can be visually recognized as a shadow, and can be recognized as a more three-dimensional pattern. Therefore, the design of the indicator design can be further improved.

According to a preferred embodiment, a plurality of the indicator symbols are arranged side by side, and the types or orientations of the indicator symbols adjacent to each other are different from each other.

Since the types or orientations of the indicator symbols adjacent to each other are different, it becomes easy for the user and the assistant to determine to which part of the indicator symbols the urine reaches.

In addition, an assistant such as a parent can be one of the triggers for communication between mother and child by transmitting information to a user such as an infant about which type or orientation the urine has reached.

According to a preferred embodiment, the indicator symbol has the function of an adhesive that adheres the sheets that make up the absorbent article.

As a result, the indicator symbol can have both a function as an indicator for detecting urine and a function as an adhesive for adhering sheets to each other.

According to a preferred embodiment, the absorbent article comprises a back sheet, an absorbent core located closer to the skin than the back sheet and absorbing the liquid, and a core wrap wrapping the absorbent core, the indicator symbol. Joins the back sheet and the core wrap.

The indicator symbol is provided at a position where the back sheet and the core wrap are joined. Therefore, the urine absorbed by the absorption core tends to come into contact with the indicator symbol via the core wrap. Therefore, once the liquid is absorbed by the absorption core, the indicator symbol easily reacts.

According to a preferred embodiment, the core wrap is joined at least in a doubly overlapping overlapping portion, and the indicator symbol is joined to a portion of the core wrap that is different from the overlapping portion.

Since the overlapping portion where the core wraps are doubly overlapped is joined by, for example, an adhesive, it is relatively difficult for urine to pass through as compared with a portion different from the overlapping portion. In this aspect, the indicator symbol is provided in a portion different from the overlapping portion, that is, in a region where urine easily passes. As a result, once the liquid is absorbed by the absorption core, the indicator symbol becomes more responsive.

According to a preferred embodiment, the absorbent article comprises an absorbent core that absorbs the liquid, a back sheet on the non-skin side of the absorbent core, and an exterior sheet on the non-skin side of the back sheet. The indicator symbol is formed on the back surface sheet, and the exterior sheet has holes at least in a region overlapping the indicator symbol in the thickness direction.

The user and the assistant visually recognize the indicator symbol provided on the back surface sheet from the non-skin surface side via the exterior sheet. Here, since the exterior sheet has holes at least in a region overlapping the indicator symbol in the thickness direction, the user and the assistant can more easily see the indicator symbol.

(2) Embodiment Next, the absorbent article according to one embodiment will be described with reference to the drawings. In this embodiment, the absorbent article is a tape-type disposable diaper. Instead, the absorbent article may be a pants-type disposable diaper. The disposable diaper may be a diaper for infants or a diaper for adults.

In the description of the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratio of each dimension is different from the actual one. Therefore, the specific dimensions, etc. should be determined in consideration of the following explanation. In addition, there may be parts in which the relations and ratios of the dimensions of the drawings are different from each other.

FIG. 1 is a plan view of the absorbent article according to the embodiment. More specifically, FIG. 1 shows a state in which the absorbent article pulled until the wrinkles are substantially eliminated is viewed from the non-skin surface side. FIG. 2 is a cross-sectional view of the absorbent article along line 2A-2A of FIG. Here, the non-skin surface or the non-skin surface side means a surface or side facing the side opposite to the wearer's skin when the absorbent article is worn. On the other hand, the skin surface or the skin surface side means the surface or side facing the wearer's skin when the absorbent article is worn.

The absorbent article 10 has a front-rear direction L, a width direction W, and a thickness direction. The anteroposterior direction L is a direction connecting the ventral side and the dorsal side of the absorbent article 10 in the worn state. The width direction W is a direction orthogonal to the front-rear direction L in a plan view of the absorbent article 10. The thickness direction is a direction orthogonal to both the front-rear direction L and the width direction W.

The absorbent article 10 has a front waist circumference area S1, an inseam circumference area S2, and a rear waist circumference area S3. The front waist circumference area S1 is a region facing the front waist circumference of the wearer when the absorbent article is used. The rear waist circumference area S3 is an area facing the rear waist circumference of the wearer when the absorbent article is used. The inseam area S2 is an area located in the inseam of the wearer when the absorbent article is used, and is located between the front waist area S1 and the rear waist area S3.

The absorbent article 10 may have a front surface sheet 50, a back surface sheet 62, and an absorber 40. The surface sheet 50 is located closer to the skin surface than the absorber 40. The surface sheet 50 covers the skin surface side of the absorber 40. The surface sheet 50 may be composed of a liquid permeable sheet.

The absorbent article 10 may have side seats 52 on both sides of the center of the absorbent article 10 in the width direction W. The side sheet 52 may be located closer to the skin surface than the surface sheet 50. In the present embodiment, the side sheet 52 is provided from the vicinity of the outside in the width direction W of the absorbent article 10 to the vicinity of the outside in the width direction W of the absorber 40. More specifically, a part of the side sheet 52 may overlap with the outer portion of the absorber 40 in the width direction W in the thickness direction.

An elastic member 30 that can expand and contract in the front-rear direction may be provided near the inside of the side sheet 52 in the width direction W. More specifically, the elastic member 30 is joined to the side seat 52 in a stretched state. As a result, the side seat 52 is naturally contracted in the front-rear direction L. Due to the contraction of the side seat 52 in the front-rear direction L, a cuff (gather) is formed in which the inner portion of the side seat 52 in the width direction stands up toward the skin side.

The back sheet 62 is located on the non-skin surface side of the absorber 40. The back sheet 62 may be composed of a non-permeable sheet. The back sheet 62 suppresses the leakage of liquid from the absorber 40 to the non-skin side.

The absorbent article 10 may have the exterior sheet 60 on the non-skin side of the back sheet 62. The exterior sheet 60 may be composed of a sheet having holes (openings) 61 in order to improve air permeability. A plurality of holes 61 may be formed in the exterior sheet 60.

The absorber 40 may have an absorption core 40a and a core wrap 40b. The absorption core 40a is made of a material capable of absorbing a liquid such as urine. The absorption core 40a may be composed of, for example, pulp, a super absorbent polymer (SAP), or a combination thereof.

The core wrap 40b may wrap the absorption core 40a. The core wrap 40b may be composed of a sheet such as tissue.

In the present embodiment, the core wrap 40b is folded back so that a pair of ends located at both ends of the core wrap 40b overlap each other on the skin surface side of the absorption core 40a in the unfolded state (see region O in FIG. 2). .. The core wrap 40b may be joined by at least a doubly overlapping overlapping portion O.

The absorbent article 10 includes an indicator symbol 80 that includes an indicator that is discolored by urine, and a back surface symbol 70 that is visible from the non-skin surface side and is different from the indicator symbol 80.

A plurality of back surface symbols 70 may be provided. The back surface symbol 70 may be provided on any sheet constituting the absorbent article 10 as long as it is visible from the non-skin surface side. For example, the back surface symbol 70 may be provided on the back surface sheet 62. The back surface symbol 70 may be colored, for example. It should be noted that the back surface symbol 70 is not composed of an indicator that reacts with urine as described later.

The indicator symbol 80 is provided at least in the inseam area S2. The indicator constituting the indicator symbol 80 can indicate the wetting of the absorbent article 10 by being discolored by urine. The indicator symbol 80 may be provided on the back sheet 62. Preferably, the indicator symbol 80 may be provided on the surface of the back sheet 62 facing the absorber 40 side.

The indicator symbol 80 includes a high weighing unit 81 and a low weighing unit 82. The high weighing unit 81 is a portion in which the material constituting the indicator is weighed more than the low weighing unit 82. The high weighing unit 81 is provided on the edge of the indicator symbol 80 in one direction, for example, the front-rear direction L. Preferably, the high weighing unit 81 is provided only on the edge of the indicator symbol 80 in the first direction.

The indicator symbol 80 changes color in response to urine. The high weighing portion 81, which has a high weighing of the indicator material constituting the indicator symbol 80, changes to a different color depending on the concentration of urine. For example, when the concentration of urine is high, the high weighing unit 81 changes to the same color as the low weighing unit 82. Further, when the concentration of urine is low, the high weighing unit 81 changes to a color different from the color of the low weighing unit 82. This is because when the concentration of urine is low, a part of the high weighing unit 81 does not react with urine.

When the concentration of urine is high, the high weighing unit 81 and the low weighing unit 82 change to substantially the same color, so that the indicator symbol 80 changes to a substantially monochromatic symbol different from the original color. Further, when the concentration of urine is low, the high weighing unit 81 and the low weighing unit 82 change to different colors, so that the indicator symbol 80 changes to a symbol containing different colors. In other words, the indicator symbol 80 can change to have a shadow when the concentration of urine is low. As a result, the indicator symbol 80 in the region where the urine concentration is low is easily recognized as a symbol which is seemingly different from the indicator symbol 80 in the region where the urine concentration is high. Here, the concentration of urine is usually highest at the place where urine first adheres and decreases with the diffusion of urine. That is, the higher the urine concentration, the higher the urine volume, and the lower the urine concentration, the lower the urine volume. Therefore, the user or assistant can easily distinguish between a region containing a large amount of urine, a region containing a small amount of urine, and a region containing no urine.

Further, even when urine is not contained, the high weighing portion 81 and the low weighing portion 82 of the indicator symbol 80 appear to be shaded, so that the design of the indicator symbol 80 can be improved. ..

When the high weighing portion 81 is provided only on the edge of the indicator symbol 80, a portion where the indicator symbol 80 may be shaded is specified on the edge in one direction. Therefore, since it is easy for the user and the assistant to grasp the position of the indicator symbol 80 where the shadow can occur, the user and the assistant can see a discolored symbol to produce some urine, that is, low-concentration urine. It becomes easier to judge whether the area is included. Further, since the high weighing unit 81 exists at the edge of the indicator symbol 80, the high weighing unit 81 can be visually recognized like a shadow and can be recognized as a figure having a three-dimensional effect. Therefore, the design of the indicator symbol 80 can be improved.

A plurality of indicator symbols 80 may be arranged at intervals in one direction. In the present embodiment, the indicator symbols 80 are arranged along the front-rear direction L. The distance L5 between the indicator symbols 80 adjacent to each other is preferably shorter than the length L4 of the indicator symbols 80 in the direction in which the indicator symbols 80 are lined up. Since the indicator symbols 80 are arranged in one direction at relatively short intervals, it becomes easy to determine to which region of the absorbent article 10 the urine reaches. It is preferable that the indicator symbol 80 reaches at least one of the front waist circumference area S1 and the rear waist circumference region S2 from the inseam region S2. More preferably, the indicator symbol 80 reaches both the front waist circumference area S1 and the rear waist circumference region S2 from the inseam region S2.

The high weighing portion 81 of the indicator symbol 80 provided in the front waist circumference area S1 is provided on either the edge on the inseam area side or the edge on the side opposite to the inseam area, and is provided in the rear waist circumference area S3. The high weighing portion 81 of the indicator symbol 80 is provided on the other side of the edge on the inseam area side and the edge on the side opposite to the inseam area. In the example shown in FIG. 1, the high weighing portion 81 of the indicator symbol 80 provided in the front waist circumference region S1 is provided on the edge on the inseam region side, and the high weighing portion of the indicator symbol 80 provided in the rear waist circumference region S3 is provided. The portion 81 is provided on the edge opposite to the inseam area.

When sleeping on his back, urine adhering to the inseam area S2 tends to flow from the inseam area S2 to the dorsal side. Therefore, even when the amount of urine is large, urine is difficult to diffuse to the ventral side. That is, in the anterior waist circumference region S1 where urine is difficult to diffuse, a high weighing portion 81 that can be used to distinguish the urine volume is provided on the inseam side, so that the user or an assistant needs to judge the urine volume more. The amount of urine can be confirmed more accurately on the inseam side.

On the other hand, when sleeping on the prone position, urine adhering to the inseam area S2 tends to flow from the inseam area S2 to the ventral side. Therefore, even when the amount of urine is large, urine is difficult to diffuse to the dorsal side. That is, in the posterior waist circumference region S3 where urine is difficult to diffuse, a high weighing portion 81 that can be used to distinguish the urine volume is provided on the inseam side, so that the user or an assistant needs to judge the urine volume more. The amount of urine can be confirmed more accurately on the inseam side.

For a user who often sleeps on his back like an infant, as shown in the example shown in FIG. 1, a high weighing portion 81 of the indicator symbol 80 provided in the front waist circumference area S1 is provided on the edge on the inseam area side. It is more preferable that the high weighing portion 81 of the indicator symbol 80 provided in the rear waist circumference area S3 is provided on the edge opposite to the inseam area.

In the plurality of indicator symbols 80, it is preferable that the high weighing portion 81 of the indicator symbol 80 is provided on the same side edge of each of the indicator symbols 80. Since the shadows of the plurality of indicator symbols 80 appear to be generated on the same side, the plurality of indicator symbols 80 have a unified atmosphere. Therefore, the design of the absorbent article as a whole is improved.

Further, since the high weighing unit 81 is located on the same side of the indicator symbol 80, the high weighing unit 81 is arranged like a memory in the front-rear direction L, for example, as shown in FIG. Therefore, the user and the assistant can more easily grasp the position of the liquid such as urine in the absorbent article 10.

The high weighing unit 81 is preferably provided on the rear edge of the indicator symbol 80. For users who often sleep on their backs, such as infants, urine adhering to the inseam area S2 tends to flow from the inseam area S2 to the dorsal side. Therefore, urine may leak from the dorsal side without noticing that the urine is diffused to the dorsal side. If the high weighing portion 81 is provided on the rear edge of the indicator symbol 80, a discoloration boundary of the indicator symbol 80 is likely to occur as the urine volume changes from the inseam region S2 to the dorsal direction. That is, in the posterior waist circumference region S3 where urine is likely to diffuse, the high weighing portion 81 that can be used to distinguish the urine volume is provided on the dorsal side, so that the user or the assistant can urinate at a position closer to the dorsal side. The amount judgment can be confirmed accurately.

It is preferable that the length of the high weighing unit 81 in one direction, for example, the length in the front-rear direction L is constant. As a result, the high weighing unit 81 is visually recognized as a shadow, and can be recognized as a pattern having a more three-dimensional effect. Therefore, the design of the indicator symbol 80 can be further improved.

Preferably, a plurality of indicator symbols 80 are arranged in a first direction, for example, in the front-rear direction L, and the types or orientations of the indicator symbols 80 adjacent to each other are different from each other. In the example shown in FIG. 1, the types of indicator symbols 80 adjacent to each other imitate a flower and a bee. Instead, the indicator symbols 80 adjacent to each other may be the same and may differ only in their orientation. As described above, when the types or orientations of the indicator symbols 80 adjacent to each other are different, it becomes easier for the user and the assistant to determine to which part of the indicator symbol 80 the urine reaches. In addition, an assistant such as a parent can be one of the triggers for communication between mother and child by transmitting information to a user such as an infant about which type or orientation the indicator symbol 80 has reached.

The indicator symbol 80 may include a region 84 surrounded by regions 82 and 83 including the indicator and not including the indicator. In this case, the high weighing unit 81 is preferably provided on the edge of the region 84 that does not include the indicator in one direction, for example, the front-rear direction L. In this case, since the high weighing unit 81 exists at the edge of the region 84 that does not include the indicator in one direction, for example, the front-rear direction L, the high weighing unit 81 is visually recognized as a shadow of the indicator symbol 80, and is more three-dimensional. It can be recognized like a sensational pattern. Therefore, the design of the indicator symbol 80 can be further improved.

The indicator symbol 80 and the back surface symbol 70 are preferably formed by related symbols. For example, in the example shown in FIG. 1, the indicator symbol 80 is composed of a flower and a bee symbol, and the back surface symbol 70 is composed of a flower and a bee symbol. As a result, a design with a sense of unity can be obtained as a whole.

In this way, the indicator symbol 80 and the back surface symbol 70 are formed of symbols that are related to each other, so that the design of the absorbent article 10 can be improved. As a result, it is possible to improve the purchasing motivation of the user and / or the user.

The indicator symbol 80 preferably has the function of an adhesive that adheres the sheets constituting the absorbent article 10. As a result, the indicator symbol 80 can have both a function as an indicator for detecting urine and a function as an adhesive for adhering sheets to each other.

Preferably, the indicator symbol 80 joins the back sheet 62 and the core wrap 40b. In this case, the urine absorbed by the absorption core 40a easily reaches the indicator symbol 80 via the core wrap 40b. Therefore, once the liquid is absorbed by the absorption core 40a, the indicator symbol 80 easily reacts.

More preferably, the indicator symbol 80 is joined to a portion different from the overlapping portion O of the core wrap 40b. Since the overlapping portion O in which the core wrap 40b is doubly overlapped is joined with an adhesive, for example, it is relatively difficult for urine to pass through as compared with a portion different from the overlapping portion O. By providing the indicator symbol 80 in a portion different from the overlapping portion O, that is, in a region where urine can easily pass through, the liquid absorbed by the absorption core 40a can easily come into contact with the indicator symbol 80. Therefore, the indicator symbol 80 becomes more responsive.

It is preferable that the hole 61 formed in the exterior sheet 60 described above is provided at least in a region overlapping the indicator symbol 80 in the thickness direction. The user and the assistant visually recognize the indicator symbol 80 provided on the back surface sheet 62 from the non-skin surface side via the exterior sheet 60. When the exterior sheet 60 has a hole 61 at least in a region overlapping the indicator symbol 80 in the thickness direction, the user and the assistant can more easily see the indicator symbol 80.

Although the present invention has been described in detail using the above-described embodiments, it is clear to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and modifications without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description of the present specification is for the purpose of exemplification and does not have any limiting meaning to the present invention.

According to this aspect, it is possible to provide an absorbent article containing an indicator that makes it easy to distinguish a region containing a large amount of urine, a region containing a small amount of urine, and a region containing no urine.
