Fiber-reinforced resin molding material molded product and method of producing same

A fiber-reinforced resin molding material molded product which is a molded product [D] comprising a fiber-reinforced resin molding material [C] prepared by impregnating chopped fiber bundles [A] obtained by cutting a reinforcing fiber bundle with a matrix resin [B], wherein in a region excluding 30 mm from an edge of the molded product [D], when an arbitrary rectangular region having an area of 40 mm2 or more and defined by a thickness of the molded product and a width in a direction perpendicular to a thickness direction of the molded product is set in a cross section in an arbitrary thickness direction of the molded product [D], with respect to a bundle thickness [E] of the chopped fiber bundles [A] present in the set rectangular region, requirements [1]-[3] are satisfied:

• [1] when a frequency distribution in which values of the bundle thickness [E] are distributed in sections set from 0 μm at intervals of every 10 μm is created, the most frequent value of the bundle thickness [E] in a section representing the highest value is 30-100 μm;
• [2] a ratio of the chopped fiber bundles [A] having a bundle thickness [E] of 200 μm or more is 5% or less;
• and
• [3] a CV value of the bundle thickness [E] is in a range of 10-60%.
