A plastic molded product includes a plastic body provided with a plurality of holes, which are recessed in a common depth direction, on a surface of the plastic body. The holes include: an inner surface including an inlet a specific reference plane perpendicular to the depth direction and including at least a portion of the inlet and a depth reference point, which is spaced away from a center point on an inlet side of the specific reference plane toward a bottom side of the hole, the depth reference point being spaced away by a distance equal to ¼ of a maximum value of an inlet side bore diameter on the specific reference plane. A deepmost portion of the inner surface of the hole is in a position which coincides with the reference point or is deeper than the reference point toward the bottom side.
