Abstract

A fiber-reinforced resin composite material has a longitudinal direction, and includes a first stack, a second stack, a ridge, a flat surface, and a connection. The ridge extends in the longitudinal direction. The flat surface is continuous to the ridge. The connection is where the first and second stacks are coupled. The first and second stacks are joined to each other in a direction intersecting the longitudinal direction. Fibers of at least one of first fiber-reinforced resin sheets included in the first stack, fibers of at least one of second fiber-reinforced resin sheets included in the second stack, or both intersect the ridge. The connection includes the first and second fiber-reinforced resin sheets that are overlapped alternately, and includes ends of the first fiber-reinforced resin sheets, ends of the second fiber-reinforced resin sheets, or both that are shifted from each other to allow the connection to have a gradually-varied thickness.
