Abstract: Provided are: a resin modifier with which flexibility, transparency and bleed resistance can be balanced at a high level; a resin composition; and a film using the same. The resin modifier includes a random copolymer composed of a structural unit derived from an aliphatic dibasic acid, a structural unit derived from an alkylenediol, and a structural unit derived from a polyalkylene ether glycol, which random copolymer has a hydroxyl group or a carboxyl group at a terminal. The polyalkylene ether glycol is preferably a polyethylene ether glycol, and the alkylenediol is preferably at least one selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3-propanediol, 2-methyl-1,3-propanediol, 1,3-butanediol, 1,4-butanediol, neopentyl glycol, 3-methyl-1,5-pentanediol, and hexanediol.
