Abstract

A fiber-reinforced resin molding material [C] includes a chopped fiber bundle [A] and a matrix resin [B], the material being characterized in that, when divided into n layers along the thickness direction of the fiber-reinforced resin molding material [C], the number-average fiber length [Lk] of the chopped fiber bundle [Ak] constituting each layer Fk (1≤k≤n) gradually increases from one outermost layer Fof the fiber-reinforced resin molding material [C] toward the other outermost layer Fn. Also provided is a molded article obtained by molding the fiber-reinforced resin molding material. This fiber-reinforced resin molding material exhibits excellent flowability, and can exhibit excellent mechanical properties when made into a molded article.
