<P>PROBLEM TO BE SOLVED: To improve heat creep resistance during use of an air conditioner or the like in a cross-flow fan made of synthetic resin using AS based resin, heat resistant PS based resin and GF(Glass Fiber), and to improve, especially in the heat resistant PS based resin, productivity by improving moldability during fan molding. Ž<P>SOLUTION: The fan is formed using the synthetic resin material characterized by mixing 20 to 40 wt.% of thin GF with diameter of 3 to 10 μm into the AS based resin or the heat resistant PS based resin, and anneal treatment is performed in a temperature range of 80 to 100°C so that the cross-flow fan having high heat creep resistance, moldability and productivity is provided.
