  • FIG. 8 is a schematic diagram showing a pattern of a pressing line EL according to the fifth embodiment.
  • a pair of squeezing lines EL extend along the front-rear direction L on both sides of the center of the absorber 40 in the width direction W.
  • the absorber 40 between the pair of squeezing lines EL is easily deformed in a convex shape toward the skin surface side because the absorber 40 is sandwiched between the legs of the user. Become. Thereby, the absorber 40 is easily fitted to the user's crotch.
  • Such a pattern of the squeezing line EL is suitably used as the absorbent body 40 for a sanitary napkin.
  • the squeezing line EL may constitute a pattern such as a symbol or a design. Even in this case, it is noted that the non-pressed portion 86 is provided at a position overlapping the pressed portion 80 of the pressed line EL different from the pressed line EL to which the non-pressed portion 86 belongs, as viewed from the width direction W. I want to.
  • FIG. 9 is a schematic diagram showing a pattern of a pressing line EL according to the sixth embodiment.
  • the plurality of squeezing lines EL extend in the front-rear direction L and are formed in a waveform that is curved in the width direction. That is, the pressing line EL extends in the front-rear direction L while wavyly curving in the width direction at a position closest to an imaginary line extending in the front-rear direction L.
  • the phases of the waveforms of the compression lines EL adjacent to each other are shifted from each other by 180 °, and the points where the compression lines EL adjacent to each other come closest to each other are connected by a compression unit along the width direction W.
  • the non-pressed portion 86 is located at a position overlapping the pressed portion 80 of the pressed line EL different from the pressed line EL to which the non-pressed portion 86 belongs, as viewed from the width direction W. Is provided.
  • FIG. 10 is a schematic diagram showing a pattern of a pressing line EL according to the seventh embodiment.
  • the pattern of the squeezing line EL is substantially the same as in the first embodiment.
  • the position of the non-squeezed portion 86 in the squeezed line EL is different from that of the first embodiment.
  • the non-pressed portion 86 is located at a position overlapping with the pressed portion 80 of the pressed line EL different from the pressed line EL to which the non-pressed portion 86 belongs.
  • at least a portion of the non-pressed portion 86 may be provided at a position overlapping the pressed portion 80 when viewed from the width direction W. Even in this case, it is difficult to form a folding base point along the width direction W, so that formation of wrinkles along the width direction W can be suppressed.
  • the entire non-pressed portion 86 is provided at a position overlapping the pressed portion 80 when viewed from the width direction W. Preferably.
  • an absorbent article including an absorbent body having a plurality of squeezed portions intermittently arranged and in which wrinkles are hardly formed in a lateral direction.
