The polyester-based resin composition according to the present invention is, at least, a polyester-based resin composition including: a polyester resin (A); a surfactant (B); and a terpene-based resin (C), in which the polyester resin (A) is obtained by copolymerizing, as a constituent component, a compound that has, as a frame, a polyalkylene glycol having a number of repeating units of from 3 to 50, in which the surfactant (B) is a non-ionic surfactant having a polyalkylene glycol frame, in which a mixing ratio (A)/(C) of the polyester resin (A) to the terpene-based resin (C) is from 80/20 to 99/1 by mass ratio, and in which the polyester-based resin composition has a water contact angle of 30° or less. |
