RESIN MEMBER, MOLD FOR MOLDING RESIN MEMBER, AND METHOD FOR MANUFACTURING RESIN MEMBER

A resin member includes: a resin substrate; and a micro-embossed pattern formed on a surface of the resin substrate and having a plurality of recesses and a plurality of protrusions. The plurality of protrusions includes: a plurality of first protrusions having a height of from 15 µm to 35 µm; and a plurality of second protrusions having a height of from 1/4 to 3/4 of the height of the first protrusions. A distance between peaks of two adjacent ones of the plurality of protrusions ranges from 100 µm to 500 µm. A plane passing through three optional lowest points having the shortest height and included in the micro-embossed pattern per unit area is used as a reference plane. If the micro-embossed pattern corresponding to a predetermined distance in a cross section perpendicular to the reference plane is divided into minute regions each having a predetermined length in the cross section, the number of the minute regions having an angle of inclination of from -10° to 10° with respect to the reference plane ranges from 78% to 95% of the number of all of the minute regions included in the micro-embossed pattern corresponding to the predetermined distance, and the number of the minute regions having an angle of inclination of from -1° to 1° ranges from 25% to 40% of the number of all of the minute regions.
