Abstract
A fiber structure for a fiber-reinforced composite material includes a section in which a width varies continuously along a central axis in a plan view. In a section in which the width increases continuously along the central axis, discontinuous fibers are aligned radially along the central axis, and both a thickness of the fiber structure and a density of the discontinuous fibers are uniform.
