A polyarylene sulfide copolymer having a glass transition temperature of 95°C or higher and 190°C or lower and having a melting point of 300°C or lower or not having melting point, as measured by differential scanning calorimetry, and the copolymer containing as a structural unit arylene sulfide units having a number average molecular weight (Mn) of 1,000 or more and 10,000 or less. A polyarylene sulfide copolymer can be provided with high physical stability such as in rigidity at high temperature and excellent moldability and chemical resistance.
