Abstract: A scroll member for scroll compressor contains a phenol aralkyl resin and a glass fiber and has feature that the dimensional change rate of the member is 0.05% or below under a chemical stability test condition conducted in an atmosphere in which a refrigerant and a refrigerating machine oil coexist at a high temperature and a high pressure, thereby making the resin scroll member practical and chemically stable. The scroll member may further contain a phenol resin and/or glass beads. The scroll member may be formed by a heat treatment having stepwise temperature increase of a molded material from an initial temperature range of 120 to 140° C. to a final temperature range of 170 to 177° C. The heat treatment can be implemented sequentially, e.g., for four hours or more at a temperature range of 120 to 140° C., for four hours or more at a temperature range of 140 to 170° C., and for four hours or more at a temperature range of 170 to 177° C.
