PROBLEM TO BE SOLVED: To provide a resin material in which property of preventing electrification is improved with various characteristics of polyacetal resin such as superior appearance, rigidity or the like maintained. SOLUTION: To polyacetal copolymer in which amount of all terminal groups is 15-150 mmol/kg (A) of 100 pts.wt. and which can be obtained by copolymerizing trioxane (a) of 100 pts.wt., compound containing two or more cycle ether unit per one molecule (b) of 0.0005-2 pts.wt. and compound containing one cyclic ether unit per one molecule (c) of 0-20 pts.wt., compound of which the basic constituent is polyalkylene ether unit (B) of 0.1-30 pts.wt. and/or fatty acid polyalcohol ester containing hydroxyl group (C) of 0.01-10 pts.wt. are compounded.
