Abstract

The purpose of the present invention is to inhibit a decrease in strength attribute to the interface between a simple-shape portion and a complicated-shape portion. This fiber-reinforced resin composite material comprises: a simple-shape portion formed from at least one sheet-shaped prepreg material obtained by impregnating reinforcing fibers with a resin; and a complicated-shape portion obtained by impregnating reinforcing fibers with a resin, the complicated-shape portion having been integrated with the simple-shape portion. The resin used for the prepreg material comprised the same components as the resin used for the complicated-shape portion.
