摘要： The fiber-reinforced resin molding material is obtained by impregnating a chopped fiber bundle with a matrix resin, has a layered structure including three or more layers in a thickness direction thereof, and satisfies the relationships Lao > Lam and Wao > Wam, where Lao and Wao represent the number average fiber length and the number average fiber bundle width, respectively, of the chopped fiber bundle in the outermost layer thereof, and Lam and Wam represent the number average fiber length and the number average fiber bundle width, respectively, of the chopped fiber bundle in a middle layer thereof. Alternatively, this fiber-reinforced resin molding material is obtained by impregnating a chopped fiber bundle with a matrix resin, has a layered structure including three or more layers in a thickness direction thereof, and satisfies the relationships Lao > Lam and Tao > Tam, where Lao and Tao represent the number average fiber length and the number-average fiber bundle thickness, respectively, of the chopped fiber bundle in the outermost layer thereof, and Lam and Tam represent the number average fiber length and the number average fiber bundle thickness, respectively, of the chopped fiber bundle in a middle layer thereof. Provided are: a fiber-reinforced resin molding material exhibiting excellent fluidity; and a molded article exhibiting excellent mechanical properties.
