Abstract
A scroll member includes a base having a panel and a spiral blade provided to extend from the panel toward another scroll member, resin layer L1 formed on the base, and a plurality of grooves C formed on a surface of the resin layer. The plurality of grooves C are formed on the surface of resin layer L1. A cross section of each groove C has a shape similar to a U-shape or a semicircle in which the width decreases toward the deeper position and the rate of change in width increases toward the bottom. Grooves C are formed by moving an edge of a cutting tool along the original surface of the resin layer, which is originally formed on base LO by application or the like.
