Description

Fishing rod and preparation method

TECHNICAL FIELD This invention relates to the pole which comprises a fishing rod, especially the pole and the manufacturing method of the pole comprised by the prepreg material which impregnates synthetic resin in reinforcement fibers, such as carbon fiber and glass fiber.

The rod used for fishing is impregnated with a synthetic resin such as epoxy resin in a reinforcing fiber called a prepreg, and the prepreg material wound into a core or sheet is wound on a core material. V) and calcined to produce it. The pole made of such a prepreg material is light and has excellent physical strength, and at the same time, it has a proper bend to fully exhibit the characteristics required for a fishing rod.

Generally, fishing rods are a favorite product or leisure goods, and individual characteristics are required for the appearance and color of the surface thereof. For this reason, a pole is also provided, in which metal plating is carried out by depositing or applying metal on the circumferential surface of the pole to produce gloss, salt, and the like as the metal.

However, as is well known, a fishing rod is largely bent when a fish caught in a gear pulls a pole when fishing, and a force is applied in the direction of breaking a pole in a large bending force or a circumferential direction. When such a force is applied to a pole, small cracks, gold, etc. may arise in the peripheral surface of the pole main body itself. In addition, such small cracks, gold, and the like are emphasized in the metal plating that gives off the luster on the circumferential surface thereof, and there is a problem that the cracked gold becomes noticeable when the fishing rod is used for a long time.

An object of the present invention is to provide a pole capable of continuing to produce good gloss and color without prominent small cracks, gold, and the like even after long-term use.

13: 층 clear layer 15: main body base

16: outer surface layer 17: carbon fiber prepreg layer

The pole of the invention 1 is made by laminating a plurality of prepreg materials impregnated with a synthetic resin in reinforcing fibers such as carbon fibers and glass fibers, and the outermost layer is made of glass fiber prepregs in which the synthetic fibers are impregnated with the reinforcing fibers of glass fibers. The pole main body, the synthetic resin layer laminated | stacked on the peripheral surface of the pole main body, the ceramic layer which physically deposited ceramic on the peripheral surface of the synthetic resin layer, and the clear layer laminated | stacked on the peripheral surface of a ceramic layer are provided.

In this pole, the glass fiber prepreg, which has relatively high elongation of the fiber itself, constitutes the outermost layer of the pole body, so that even if a large bending strength or the like is applied to the pole, cracks rarely occur, and even if cracks occur, It is hard to lose. On the other hand, the layer which improves the designability of the pole main body circumferential surface is a physical vapor deposition of the ceramic which was excellent in hardness to the synthetic resin layer, and there is very little possibility that a crack will generate | occur | produce itself.

In addition, in such a long manufacturing process, in order to physically vapor-deposit a ceramic to a pole circumferential surface, it is necessary to smooth the deposited surface and the pole body circumferential surface is smoothed in a synthetic resin layer, but the pole body is further In order to smooth the circumferential surface itself, a surface treatment for polishing is also required. At this time, since the circumferential surface of the pole main body is comprised from the glass fiber prepreg with comparatively small hardness, surface polishing process also becomes easy.

In the pole of the second invention, in the pole of the first invention, the ceramic layer is metal nitride or metal oxide such as CrN, TiN, TiO ₂ or the like.

In this pole, by forming a ceramic layer made of metal nitride or metal oxide such as CrN, TiN, TiO ₂ or the like, the strength of itself can be sufficiently increased, and beautiful gloss and salt can be produced.

The pole of invention 3 is the pole of invention 1 or 2 WHEREIN: The pole body outer surface is a glass fiber prepreg which has the carbon fiber prepreg which carbon fiber couple | bonded in the circumferential direction, and the glass fiber of the circumferential direction laminated | stacked on the outer peripheral surface. Consists of.

Although the glass fiber prepreg is located in the outermost peripheral surface of this pole pole body as mentioned above, glass fiber is inferior to an elastic modulus as compared with carbon fiber. For this reason, the rigidity of the pole circumferential direction may be insufficient. Therefore, the carbon fiber prepreg in which the carbon fibers are bonded in the circumferential direction disposed adjacent to the inner circumference thereof sufficiently compensates the rigidity in the pole circumferential direction slightly insufficient by the glass fiber prepreg alone to increase the stiffness of the pole.

In the pole of invention 4, the pole of invention 3 WHEREIN: A glass fiber prepreg is a thin prepreg material with an average thickness of about 0.010 mm-about 0.020 mm.

In this pole, since a predetermined carbon fiber prepreg is disposed in close proximity to the inside of the glass fiber prepreg, the glass fiber prepreg itself does not need to be thickly stacked, and it is sufficient to exist only enough to prevent small cracks on the surface. Specifically, the glass fiber prepreg is sufficient to have a thickness of a predetermined range and contributes to the weight reduction of the pole itself.

Moreover, the pole according to the present invention is characterized in that a ceramic layer in which ceramics are physically deposited on the outside of the pole body is provided.

In such a pole, since a ceramic layer is hard compared with a metal, it is hard to produce a flaw in a ceramic layer, and a small crack and a crack do not generate easily. In addition, beautiful luster and color development can be obtained as in the case of a layer made of metal. Therefore, good gloss and color can be maintained over a long period of use.

In addition, in the case where the pole body is formed by firing a fiber-reinforced synthetic resin material containing carbon fibers as the reinforcing fiber, a lower ceramic layer and an upper ceramic layer are provided on the outer side of the pole body and the lower ceramic layer is provided. The silver is preferably configured to develop a single color, and the upper ceramic layer is preferably configured to develop a rainbow color. Furthermore, the fiber reinforced synthetic resin material has a prepreg material, for example.

In the case of containing carbon fiber, the pole body is blacked by carbon fiber by firing, but in this case, black is provided by sandwiching the lower ceramic layer that is colored in a single color inside the upper ceramic layer that is colored in rainbow colors. Since the pole main body of is covered by the lower ceramic layer, the color of the rainbow color in the upper ceramic layer is better than in the case where the lower ceramic layer is not provided.

Moreover, when the pole main body is formed by baking the fiber reinforced synthetic resin material containing carbon fiber as a reinforcing fiber, the said ceramic layer is provided in the outer side of the said pole main body with the black synthetic resin layer interposed. It is preferable. Although only a portion of the carbon fiber may be particularly prominent on the surface of the pole body, since the surface of the pole body is covered by the black synthetic resin layer, a ceramic layer is formed on the uniform black, thus exhibiting a loose shape. Color development of a good ceramic layer is ensured without work. In addition, the fiber reinforced synthetic resin material has a prepreg material, for example.

Moreover, the manufacturing method of the pole according to this invention is characterized by forming a ceramic layer by sputtering on the outer side of a pole main body.

In the said manufacturing method, since a ceramic layer is formed by sputtering, compared with another method, for example, the method of forming by ion plating, the ceramic layer of uniform thickness can be formed easily. If the thickness of the ceramic layer is not uniform, a good monochromatic ceramic layer is not formed. However, by forming a ceramic layer by sputtering, a ceramic layer having a uniform thickness can be obtained, so that a ceramic layer exhibiting a good monochromatic color can be easily obtained. .

In particular, it is preferable to form a ceramic layer made of metal nitride using metal nitride as a target. In the case of forming a ceramic layer made of metal nitride, it is conceivable to form a reactive metal plating method in which a metal other than nitride is reacted with nitrogen gas (reactive gas) to deposit metal nitride, but in reactive ion plating It was difficult to form a ceramic layer made of a good metal nitride. On the other hand, according to sputtering which targets metal nitride itself, the ceramic layer which consists of favorable metal nitride can be formed to firmly and uniform thickness.

In this case, a ceramic layer of metal nitride can be formed at low cost by using a sintered body of metal nitride as a target.

The fishing rod described in this embodiment is a so-called barrel fishing rod, and a fishing line inlet 6 for introducing a fishing line from the reel to the rod body is formed on the waterline side circumferential surface of the reel seat 5 of the rod 1. On the circumferential surface thereof, a fishing line introduction guide 7 for guiding the fishing line in the fishing line introduction port is arranged.

On the other hand, the top guide 8 is connected to the waterline side end of the chord 4, and the fishing line drawn from the fishing line inlet 6 into the pole body is sequentially sent to the waterline side and drawn out from the top guide 8 to the outside.

(Structure and Manufacturing Method of Company 2)

The structure and manufacturing method of each pole will be described taking the squadron 2 as an example.

As schematically shown in Fig. 2, the core 2 is a carbon fiber reinforced resin in which carbon fibers are impregnated with a synthetic resin such as an epoxy resin, or a glass fiber reinforced with glass fiber impregnated with a synthetic resin such as an epoxy resin. It is a cylindrical member formed by laminating | stacking, baking, and integrating the prepreg sheet prepreg tape which consists of resin etc. sequentially. And ceramics are physically deposited on the circumferential surface.

Specifically, the pole main body 10 which consists of several prepreg sheet prepreg tape, the synthetic resin layer 11 laminated | stacked on the circumferential surface of the pole main body 10, and the circumferential surface of the synthetic resin layer 11 And a clear layer 13 laminated on the circumferential surface of the ceramic layer 12.

The pole main body 10 is composed of an outer surface layer 16 laminated on the circumferential surface of the main body base 15 and the main body base 15, although the structure thereof will become clear in more detail in the manufacturing method described later. do. The outer surface layer 16 is composed of a carbon fiber prepreg layer 17 and a glass fiber prepreg layer 18.

The synthetic resin layer 11 is a layer for smoothing the peripheral surface of the pole main body 10 and making physical vapor deposition of the ceramic layer 12 easy and sufficient, For example, it consists of epoxy resin, a urethane resin, etc. In addition, the synthetic resin layer 11 (base lacquer) may not be limited to the single | mono layer of a single lacquer, and the multilayer which applied several times may be sufficient as it.

The ceramic layer 12 is obtained by closely laminating a ceramic such as metal nitride or metal oxide such as CrN, TiN, TiO ₂ or the like on the synthetic resin layer 11 described above by a known physical vapor deposition method such as sputtering or ion plating. Compared to the case of using a simple metal which is not nitrided or oxidized, it is excellent in strength and durability by using ceramic material. That is, compared with the case where the layer which consists of metals which are not nitrided and oxidized is made, the ceramic layer 12 has the advantage that hardness is high, therefore a flaw is hard to generate | occur | produce and a small crack and a crack rarely generate | occur | produce. In addition, it is possible to obtain beautiful gloss and color as in a layer made of metal, to produce good gloss and color, and to be excellent in design.

The clear layer 13 is a transparent or translucent synthetic resin layer for protecting the ceramic layer 12, and may be appropriately colored as necessary. In addition, the clear layer 13 (top coat) is not limited to the single | mono layer of single coating, but may be a multilayer which it painted several times.

Next, the structure of the pole main body 10 will be described while explaining the manufacturing method sequentially.

As shown to Fig.3 (a), the cylindrical core material 50 which becomes thinner toward the front end is prepared, and the release surface etc. are apply | coated to the circumferential surface as needed. Then, for example, the prepreg 51 for reinforcement is wound partially at the waterline side end part which is hardened | cured and the other place where reinforcement is needed. This reinforcement prepreg 51 is a prepreg which combined the reinforcing fiber of either carbon fiber or glass fiber in the circumferential direction of the core material 50.

Next, as shown in (b) of FIG. 3, the prepreg tape 52 processed in the shape of a tape in a spiral shape without a gap in the axial direction is formed on the outer circumference of the core 50 and the reinforcement prepreg 51. Wind up. For example, the prepreg tape 52 has a tape width of about 5 to 8 mm in which carbon fibers are bonded in the longitudinal direction of the tape, and the tensile modulus of the carbon fibers is preferably about 24 to 50 t / mm ² .

As shown in FIG.3 (c), the prepreg sheet 53 is rolled separately to the outer periphery which wound this prepreg tape 52. FIG. A plurality of sheets of the prepreg sheet 53 are sequentially wound as necessary. The prepreg sheet 53 is, for example, a carbon fiber is bonded in the axial direction of the core material 50, and has a tensile modulus of about 30 to 60 t / mm ² , which is larger than that of the prepreg tape 52 described above. Is preferable. When winding up the several prepreg sheet 53, the characteristic of the carbon fiber of each prepreg sheet 53 to be wound may be different. In addition, each prepreg tape sheet | seat to here constitutes the main body base layer 15 of the pole main body 10 shown typically in FIG.

As shown in Fig. 3 (d), the prepreg tape 54 in which carbon fibers are bonded in the longitudinal direction of the tape is wound in a spiral shape on the outer circumference of the prepreg sheet 53 wound in this way. The prepreg tape 54 has a width of about 5 to 8 mm and the tensile modulus of carbon fiber is about 24 to 30 t / mm ^{2, similar} to the prepreg tape 52 described above. This prepreg tape 54 becomes the carbon fiber prepreg layer 17 of the outer surface layer 16 which is typically shown in FIG.

As shown in FIG.3 (e), the glass prepreg sheet 55 which woven the glass fiber in the circumferential direction and the axial direction of the core material 50 is further wound on the outer periphery. The glass fiber of this glass prepreg sheet 55 has a tensile modulus of elasticity smaller than that of carbon fiber, and is about 6 to 8 t / mm ² . It is preferable that content of synthetic resin is also comparatively small, For example, the content rate of synthetic resin shall be about 20 to 30%. In addition, since the glass prepreg sheet 55 is preferably laminated relatively thinly in order to reduce the weight, it is preferable to use an average thickness of about 0.010 to 0.020 mm. And this glass prepreg sheet 55 turns into the glass prepreg sheet layer 18 in FIG. In place of the glass prepreg sheet 55, the same glass prepreg sheet may be wound around a tape-shaped prepreg tape in which the same glass prepreg sheet is slit about 5 to 8 mm wide like the prepreg tapes 52 and 54.

After winding each prepreg sheet tape in this way, as shown in FIG.3 (f), the prepreg 56 for reinforcement is further partially wound up as needed, and the polypropylene, The molding tape 57 made of synthetic resin such as polyester is wound while applying a spiral tension. This reinforcement prepreg 57 is wound for reinforcement or for reinforcement of the engagement portion of the pole, for example, to a place such as the fishing line inlet 6 in the rod 1, and then squeezed nylon fiber. It is also possible to use a prepreg impregnated with a synthetic resin.

Each of these prepregs is fired in a furnace. Thereby, each prepreg is integrated. Subsequently, the shaping | molding tape 57 is peeled off, the core material 50 is pulled out, the both ends are cut | disconnected, it adjusts to an appropriate length, and the circumferential surface is polished and smoothed, and the pole main body 10 is manufactured.

Thereafter, as described above, the synthetic resin is applied to the peripheral surface to form the synthetic resin layer 11, and the peripheral surface is smoothed to physically deposit ceramics to form the ceramic layer 12, and the clear layer 13 By constructing the poles such as squadron (2).

In detail, the process of forming the ceramic layer 12 by physical vapor deposition will be described in detail. Among the physical vapor deposition, the ceramic layer 12 is preferably formed by sputtering or ion plating, and has a high density of pinholes. ) Can be obtained.

Moreover, it is especially preferable to form by sputtering. That is, in the case of ion plating, tungsten is also slightly evaporated and attached to the pole main body 10 in order to attach the ceramic to a filament made of tungsten or the like, which may lower the purity of the ceramic layer 12. . On the other hand, in the case of sputtering, since the target ceramic can be attached as it is, there is an advantage that the high purity ceramic layer 12 can be easily obtained.

In addition, in the case of sputtering, there is also an advantage that it is easy to form the ceramic layer 12 having a uniform thickness. For example, when it is desired to obtain a good monochromatic color, it is necessary to make the thickness of the ceramic layer 12 uniform with high accuracy. However, in the case of ion plating, in the case of sputtering, it is extremely difficult to control the thickness. The ceramic layer 12 of uniform thickness can be obtained easily, and the favorable monochromatic ceramic layer 12 can be obtained. In addition, for example, in the case of chromium nitrides (CrN, Cr ₂ N), a dark silver or silver metal color can be obtained, and titanium nitride (TiN) can be obtained a gold metal color (ie, golden color).

In addition, when the ceramic layer 12 is a metal nitride, since the high purity ceramic layer 12 can be obtained by sputtering, the color development of monochromatic color can be further improved, and a uniform thickness can be obtained and a good color development can be obtained. Can be. In particular, among the metal nitrides, in the case of chromium nitride, the ceramic layer 12 made of high chromium nitride with good sputtering properties can be uniformly attached with high adhesion.

Here, the case where the ceramic layer 12 which consists of chromium nitride is formed about the method of forming the ceramic layer 12 by sputtering is demonstrated, for example. First, chromium nitride (for example, CrN) is used as a target, and especially the sintered compact of chromium nitride is used. For example, the method of forming the ceramic layer 12 which consists of chromium nitride by making chromium react with nitrogen gas which is a reactive gas can also be considered, but in this method, the ceramic layer 12 which consists of chromium nitride is formed. It is not easy to do In contrast, by using chromium nitride as the target, it is possible to easily form the ceramic layer 12 made of high purity chromium nitride. Moreover, using a sintered compact can suppress manufacturing cost.

As described above, an example of a method of forming the ceramic layer 12 made of chromium nitride by sputtering will be described. A sputtering apparatus for this purpose is provided with a target on the outer wall of the vacuum container, and the inside of the vacuum container has a pole body ( 10) is configured to rotate while rotating. In other words, the rod main body 10 rotates while turning around the front of the target. Using this sputtering apparatus, the vacuum vessel is evacuated to 7 × 10 ⁻⁵ Torr, nitrogen gas is introduced into the vacuum vessel to 3 × 10 ⁻⁴ , and argon gas is then 3 × 10 ^{−3 in the} vacuum vessel. To be introduced. Then, while rotating and rotating the rod main body 10 to be the object, direct current power is applied to the pole main body 10, and sputtering is performed using chromium nitride as a target. For example, DCA of 2.5 A x 600 V (= 1.5 KW) is applied for 20 minutes to form a film of chromium nitride having a thickness of 600 kV. Here, nitrogen gas may not be introduced.

As for the poles, such as the pole 2 manufactured in this way, the glass prepreg sheet layer 18 comprises the outermost layer of the pole main body 10, and a crack does not hardly generate | occur | produce, even if a large bending force etc. are applied to a pole. Even if a crack occurs, it is hard to spread further. On the other hand, the ceramic layer 12 composed of metal nitrides or metal oxides such as CrN, TiN, TiO _2, and the like is physically deposited on the synthetic resin layer 11, so that there is little risk of cracking itself. For this reason, the crack main etc. which generate | occur | produce in the circumferential surface from the pole main body 10 can fully be prevented from damaging an external appearance. In addition, since the outermost layer of the rod main body 10 is easily polished as the glass prepreg sheet layer 18, the peripheral surface smoothing for physical vapor deposition of the ceramic is also easy.

In addition, the outer surface layer 16 of the pole main body 10 is comprised from the carbon fiber prepreg layer 17 and the glass prepreg layer 18, and carbon in the circumferential direction from the inner periphery of the glass fiber prepreg layer 18 is carried out. The carbon fiber prepreg layer 17 in which the fibers are bonded complements the stiffness in the circumferential direction, and the long bending strength can be sufficiently maintained by the relatively thin glass fiber prepreg layer 18.

[Other Example]

The manufacturing method demonstrated in the said Example is an example to the last, and the following method can also be illustrated to the method of forming the outer surface layer 16 of the pole main body 10, for example.

(a) As shown in FIG. 4, after forming the part corresponding to the main body base 15 of the pole main body 10 by the predetermined | prepreg, carbon fiber is made to the outer periphery in the circumferential direction of the core material 50. FIG. The bonded carbon prepreg sheet 64 is prepared and wound up. And the glass prepreg sheet 65 is wound around the outer periphery. Unlike the above embodiment, the glass prepreg sheet 65 may be woven in a cross direction oblique to the core 50. In this case, since the glass prepreg sheet 65 covers the last seam of the carbon prepreg sheet 64 bonded in the circumferential direction, there is an effect that the crack of the surface layer can be prevented.

(b) As shown in FIG. 5, after forming the part corresponding to the main body base 15 of the pole main body 10 by the predetermined | prepreg, carbon fiber is made to the outer periphery in the circumferential direction of the core 50 The bonded carbon prepreg sheet 74 is prepared and wound up. And the method of spirally winding a glass prepreg tape in the outer periphery can also be considered.

In forming the outer surface layer 16, the carbon fiber prepreg sheet is wound to form the carbon fiber prepreg layer 17 by winding the carbon fiber prepreg sheet in the same manner as in the above embodiment, and then the glass prepreg sheet is wound in a spiral shape to glass fiber prepregs. There is also a method of forming the leg layer 18. Furthermore, the carbon fiber prepreg layer 17 may be formed from the carbon fiber prepreg tape, and the glass fiber prepreg layer 18 may be wound to form the glass fiber prepreg layer 18.

(c) The carbon prepreg sheet 74 can also use a carbon fiber bonded to the axial direction of the core material 50.

In addition, in the said embodiment, although what comprised the outermost layer glass fiber prepreg of the pole main body 10 was demonstrated, the structure of the pole main body 10 can also be variously changed.

For example, the pole body 10 of the pole 2 (pole) shown in FIG. 6 is the outer surface layer 16 laminated | stacked on the main body base 15 and the outer peripheral surface of the said main body base 15 like the structure of FIG. ), But differs from the configuration of FIG. 2 in that the outer surface layer 16 does not have a glass fiber prepreg layer 18. That is, in the pole main body 10 shown in FIG. 6, the outer surface layer 16 whole is comprised by the carbon fiber prepreg layer. As described above, the layer structure of the rod main body 10 can be variously changed, and thus, the reinforcing fibers can be changed as appropriate. However, as the main configuration of the pole body 10, the reinforcing fibers can be mixed in the innermost layer in the circumferential direction, and the reinforcing fibers are bonded in the axial direction of the pole body 10 in the middle layer, which is the main part of the pole body 10. In the outermost layer, the reinforcing fibers can be bonded in the circumferential direction.

Here, when the pole shown in FIG. 6 is demonstrated in more detail, the pole is formed in the multilayered ceramic layer through the transparent synthetic resin layer 11 outside the pole main body 10. Specifically, the ceramic layer 12 is composed of the lower ceramic layer 122 and the upper ceramic layer 121, the lower ceramic layer 122 is laminated on the outer peripheral surface of the synthetic resin layer 11, the upper ceramic layer The 121 is laminated on the outer circumferential surface of the lower ceramic layer 122. A clear layer 13 is formed on the outer circumferential surface of the upper ceramic layer 121 as described above.

The lower ceramic layer 122 and the upper ceramic layer 121 may be the same kind of ceramics, but preferably different kinds of ceramics. For example, the lower ceramic layer 122 may be made of metal nitride, and the upper ceramic layer 121 may be made of metal oxide. CrN is a metal nitride and TiO ₂ is a metal oxide.

As described above, when the upper ceramic layer 121 made of the metal oxide and the lower ceramic layer 122 made of the metal nitride are laminated, it is also possible to form both layers 121 and 122 by sputtering. It is also possible to deposit metal nitride by sputtering and to deposit metal oxide by ion plating.

That is, when the lower ceramic layer 122 is made of metal nitride, it is formed by sputtering, and when the upper ceramic layer 121 is made of metal oxide, it is formed by ion plating (especially reactive ion plating). can do. In the case of forming in this way, the lower ceramic layer 122 having a uniform thickness is formed by sputtering, so that a good monochromatic color can be obtained first. On top of this, the upper ceramic layer 121 having a complicated thickness can be formed by ion plating again, so that the upper ceramic layer 121 can be obtained in a rainbow color by interference. In this manner, when the two ceramic layers 121 and 122 are formed, the pole itself is colored in rainbow colors by the upper ceramic layer 121 as a whole. In addition, when the lower ceramic layer 122 is chromium nitride (CrN) formed by sputtering and the upper ceramic layer 121 is TiO ₂ formed by ion plating, the whole pole becomes a metallic color which is colored in rainbow colors. .

In this way, when forming a ceramic layer which is colored in rainbow colors by ion plating, it is also possible to form it directly on the rod main body 10 or directly on the synthetic resin layer 11, for example, It is preferable to form the lower ceramic layer 122 as described above on the synthetic resin layer 11.

In other words, by forming the lower ceramic layer 122 that is colored in a single color inside the upper ceramic layer 121 that is colored in a rainbow color, the color of the rainbow color is improved. When carbon fiber is contained in the reinforcing fiber of the rod main body 10, it will be baked (heat-hardened), and the pole main body 10 will become black by carbon fiber. Therefore, when only the ceramic layer which develops in a rainbow color is formed in the outer side of the black pole main body 10, since the foundation is black, rainbow color development may not necessarily be good. On the other hand, the lower ceramic layer 122 is provided inside the upper ceramic layer 121, and the black pole body 10 is covered by the monochromatic lower ceramic layer 122 so that it is positioned outside. The color of the rainbow color in the upper ceramic layer 121 is improved. In addition, even when the upper ceramic layer 121 is a single color, the color of the upper ceramic layer 121 is improved by forming the lower ceramic layer 122 therein.

In addition, in the example of FIG. 5, although the ceramic layer 12 was two layers of upper and lower layers, it may be three or more layers, of course.

In addition, in the case of the rod main body 10 using at least one portion of carbon fibers as the reinforcing fibers, the synthetic resin layer 11 may be black, for example, in addition to making the synthetic resin layer 11 transparent. When only a portion of the carbon fiber is particularly thick on the outer circumferential surface of the rod main body 10, color development of the ceramic layer 12 formed on the outer side by forming such a black synthetic resin layer 11 is performed. It is preferable because there is no phenomenon of becoming coarse due to the influence of the carbon fiber determination.

In addition, although the tubular squadron 2 was demonstrated as an example as a pole, a solid pole may be sufficient.

According to the present invention, it is possible to provide a fishing rod capable of maintaining the appearance of excellent gloss and salt over a long period of time.
