摘要： A resin molded article having a moveable projecting portion suitable for use in forming a keyboard or keyboard switch and which is substantially free from flex fatigue. At least the moveable projecting portion of the molded article is formed from a resin composition containing a polyether ester block copolymer and a small amount of an alkali metal salt of an aliphatic carboxylic acid having 10 to 36 carbon atoms. The polyether ester block copolymer contains units from terephthalic acid, tetramethylene glycol and polyoxytetramethylene glycol. The resin molded article includes a thick projecting (moveable) portion, a base portion and a flexible thin side portion connecting the thick projecting portion to the base portion. The side portion has a thickness of 0.05 to 0.5 mm and a flexibility retention of at least 85%.
