Abstract: A fiber-reinforced resin shaped product includes: reinforcing fibers with a weight average fiber length of 100 mm or less; and a thermoplastic resin. The fiber-reinforced resin shaped product has grains on at least a part of a surface thereof. A maximum height (Rz) of the grains is 100 μm to 200 μm, and an average pitch (Rsm) between adjacent grains is 1100 μm or less.

Abstract: Provided is a fiber-reinforced resin shaped product including reinforcing fibers and a thermoplastic resin and having grains on at least a part of a surface thereof. The ratio of a maximum reflectance (R) to a half-value width (H), each of which is obtained by goniophotometric measurement satisfies Expression (1): R/H≤0.034×R−0.15 (1). In the expression, R is a maximum reflectance (%), and H is a half-value width (degree).
