Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the subject casing which can simultaneously develop excellent antistatic properties, electromagnetic shielding properties, light weight and high stiffness and is particularly useful for casing of portable electronic appliances by molding a fiber-reinforced resin composition containing carbon fibers and a specific polyamide. SOLUTION: A resin composition containing (A) carbon fibers and (B) a semiaromatic polyamide (for example, a polymer from an aromatic diamine and an alipahtic dicarboxylic acid) (B1 ) and an aliphatic polyamide (for example, nylon 6, nylon 66) (B2 ) in which the weight ratio of B1 /B2 is (10-90)/(90-10) are molded so that the weight ratio of A/B becomes (10-45)/(90-55).
