Rod body for fishing rod and fishing rod provided therewith

A rod body for a fishing rod, comprising

• a main body layer formed, in a cylindrical shape, from a prepreg, wherein
• the main body layer includes a small-diameter part positioned at a front side, a large-diameter part positioned at a rear side, and a steeply-expanded diameter part positioned between the small-diameter part and the large-diameter part,
• both an inner and an outer diameters of the steeply-expanded diameter part are expanded toward the rear side by a steeper incline than the incline of the small-diameter part and the incline of the large-diameter part,
• of the entire length of the main body layer, a predetermined-length region including at least the steeply-expanded diameter part is configured by a layer formed, in a cylindrical shape, from a main part and a complementary part,
• the main part is formed by a main prepreg having a length corresponding to the predetermined-length region, and in the small-diameter part, the main prepreg is wound over the entire circumference in a circumferential direction with both ends of the main prepreg in the widthwise direction overlapping each other, and in the large-diameter part, the main prepreg is wound so that a part of the entire circumference in the circumferential direction remains behind as a winding-shortage part, with both ends of the main prepreg in the widthwise direction separated from each other in the circumferential direction, and
• the complementary part is formed to complement the winding-shortage part by a sub-prepreg having a predetermined shape corresponding to the winding-shortage part.
