Abstract: The toughness of a laminate is improved. A fiber-reinforced resin material contains a fiber material in a resin; and the fiber material contains high-rigidity fibers and fibroin fibers. According to the present invention, a laminate is formed by laminating and bonding a plurality of fiber-reinforced resin layers. A fiber-reinforced resin layer contains the high-rigidity fibers in a resin. A fiber-reinforced resin layer contains the fibroin fibers in a resin.
