PROBLEM TO BE SOLVED: To provide a rod body for a fishing rod, simply producible by a worker even with a low level of skill, and a fishing rod using the same.SOLUTION: A rod body for a fishing rod includes a body layer which is formed in a cylindrical shape from prepregs 71a, 71b, and 71c, and which includes a suddenly-enlarged diameter part whose inclination is sharper than those of front and back areas and which is enlarged in both inner and outer diameters toward the back side. A prescribed-length area including at least the sudden-enlarged diameter part in the entire length of the body layer has a layer having a cylindrical shape with one round by arranging and winding, while forming an overlapped portion, a plurality of sheets of the prepregs 71a, 71b, and 71c having a length corresponding to the prescribed-length area, in the circumferential direction, so as to form each division area formed by dividing one round into a plurality of areas by using each sheet of the prepregs 71a, 71b, and 71c.COPYRIGHT: (C)2014,JPO&INPIT【課題】作業者の熟練度合いが低くても簡単に製造することができる釣竿用竿体とそれを用いた釣竿を提供する。【解決手段】プリプレグ71a,71b,71cから筒状に形成された本体層を備え、該本体層は前後の領域の勾配よりも急勾配で後側に向けて内外径共に拡径する急拡径部を備えている釣竿用竿体であって、本体層の全長のうち少なくとも急拡径部を含む所定長さ領域は、一周を複数に分割した各分割領域をそれぞれ一枚のプリプレグ71a,71b,71cにより形成すべく、前記所定長さ領域に対応した長さを有する複数枚のプリプレグ71a,71b,71cを重ね合わせ部を形成しつつ周方向に並べて巻回することにより一周分とされた筒状の層を有している。【選択図】図3
