Resin member, mold for molding resin member, and method for manufacturing resin member

A resin member comprising:

• 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, wherein
• a plane passing through three optional lowest points that are deepest points included in the micro-embossed pattern per unit area is used as a reference plane, and a shortest distance from the reference plane to an optional point on the micro-embossed pattern is regarded as a height of the micro-embossed pattern,
• 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 ¼ to ¾ 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,
• 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.
