Abstract
Provided is a fiber-reinforced resin material molding in which fluctuations of the dispersion state of the fiber bundle in the molding is small, the generation of a resin pool is suppressed, and fluctuations in physical properties such as tensile strength and modulus of elasticity are suppressed; a method for manufacturing the same, and a method for manufacturing a fiber-reinforced resin material. Provided is a fiber-reinforced resin material molding comprising: a fiber bundle comprising a plurality of reinforcing fibers; and a matrix resin, wherein a coefficient of variation in fiber content of the reinforcing fibers per unit zone of 0.1 mm square on a cut face along a thickness direction is 40% or less.
