PROBLEM TO BE SOLVED: To provide a rod body for a fishing rod which has a low flexural rigidity on the vicinity of a tip end thereof and has a high flexural rigidity on the vicinity of a base end thereof.SOLUTION: A rod body for a fishing rod comprises: a body 11 formed of a first material which is formed into a tabular shape extending in a longitudinal direction from a base end to a tip end； and reinforcement bodies 12 each of which is provided on each of both ends in a width direction of the body 11 and formed of a second material having a Young ratio larger than that of the first material. The reinforcement body 12 has a first width at a first position in the longitudinal direction, and has a second width being smaller than the first width at a second position 2b which is closer to the tip end than the first position 2a in the longitudinal direction.SELECTED DRAWING: Figure 2【課題】先端付近で低い曲げ剛性を有するとともに基端付近で高い曲げ剛性を有する釣竿用竿体を提供する。【解決手段】釣竿用竿体は、基端から先端に向かう長さ方向に伸びる板状に形成された第１の材料から成る本体１１と、前記第１の材料よりも大きなヤング率を有する第２の材料から成る、前記本体１１の幅方向両端に設けられた補強体１２と、を備える。前記補強体１２は、前記長さ方向の第１の位置において第１の幅を有し、前記長さ方向の前記第１の位置２ａよりも前記先端寄りにある第２の位置２ｂにおいて前記第１の幅よりも小さな第２の幅を有するように形成されている。【選択図】図２
