Abstract
A composite material member having an FRP layer made of fiber-reinforced plastic, and a resin-rich layer that has a fiber content that is 5% or less of the fiber content of the FRP layer. The resin-rich layer is formed in at least a partial region of a surface of the FRP layer, and is formed from the same resin as a matrix resin of the fiber-reinforced plastic. A hole is bored so as to penetrate the FRP layer and the resin-rich layer.
