2. Description of the Related Art A resin composition comprising an aromatic polycarbonate resin and a thermoplastic aromatic polyester resin is widely used in various industrial fields as a material having excellent mechanical properties, thermal properties, chemical resistance and the like.

Japanese Patent Application Laid-Open No. 4-253766 discloses that a specific ultra-high molecular weight polycarbonate is used to improve the drawdown property of a polycarbonate resin. In recent years, however, in the field of automobile parts, chemical resistance and impact resistance have been improved. There has been a demand for a composition having an excellent balance of properties such as high rigidity.

A resin composition comprising an aromatic polycarbonate resin reinforced with a fibrous filler such as glass fiber and a thermoplastic aromatic polyester resin has a mechanical property such as rigidity due to the blending of the fibrous filler such as glass fiber. It is a material excellent not only in chemical resistance but also in drawdown characteristics, and is used in various industrial fields for blow molding.

However, a resin composition comprising an aromatic polycarbonate resin reinforced with a fibrous filler such as glass fiber or carbon fiber and a thermoplastic aromatic polyester resin is blow-molded at a normal mold temperature (100 ° C. or lower). In this case, the fibrous filler such as glass fiber or carbon fiber floats on the surface to form a Japanese paper pattern. The disadvantage is that it must be thicker. Also, a very high mold temperature (120
(130 ° C. to 130 ° C.), it is possible to obtain a molded article having a good appearance to some extent,
There is a problem that the molding cycle is lengthened and the productivity is significantly reduced.

Further, as a method for improving the rigidity of the resin composition, a method of blending a scaly or plate-like inorganic filler such as talc or mica (JP-A-55-129444, JP-A-5-222283) ) Is disclosed.
