摘要： A resin member includes: a resin substrate; and a micro-embossed pattern and having a plurality of recesses and a plurality of protrusions. The plurality of protrusions includes: a plurality of first protrusions; 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. 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.
