Abstract
A void-containing resin molded product consisting of a polymer having crystallinity, wherein the void-containing resin molded product has elongated voids whose longitudinal directions are aligned in one direction, wherein the elongated voids satisfy the expression h(avg)>T/100, where h(avg) denotes an arithmetic average of h(i)s which each denote a distance from a surface of the void-containing resin molded product to a center of each of 10 voids whose centers are closer to the surface of the void-containing resin molded product than are centers of any other voids in a cross-section of the void-containing resin molded product that is perpendicular to a direction in which the voids are aligned, the 10 voids being selected from voids in a region defined by one straight line which is parallel to a thickness direction of the void-containing resin molded product and another straight line which is parallel to and distant by 20×T from the one straight line; and T denotes an arithmetic average thickness of the cross-section, and wherein the elongated voids have a ratio L/r of 10 or more, where L denotes an average length of the voids (in μm) in a direction in which the voids are aligned, and r denotes an average length of the voids (in μm) in a thickness direction which is perpendicular to the direction in which the voids are aligned.
