An object of the present invention is to provide a polylactic acid series card material combining excellent mechanical strength and resistance to hydrolysis even when a polylactic acid series polymer is used as a main component, and in addition, maintaining a sufficient transparency even when an aliphatic polyester is added. The present invention comprises, with respect to 100 parts in mass of resin composition constituted by 50 to 90 mass% of a polylactic acid series polymer (a), and 50 to 10 mass% of an aliphatic polyester (b) other than polylactic acid series polymer and having a glass transition temperature (Tg) of 0°C or lower, 0.3 to 6 parts in mass of an aliphatic polycarbodiimide compound (c) having an isocyanate end further mixed. |
