A biodegradable card which is easy to cut and excellent in capability of inscription of a letter by embossing and in tensile strength, impact strength, thermal resistance, and the like, characterized in that it is manufactured of a laminate comprising a core layer containing, as a main component, a composition comprising 40 to 90 wt.% of a poly(lactic acid) and 60 to 10 wt.% of a biodegradable aliphatic polyester having a glass transition temperature (Tg) of 0 °C or lower and, laminated on both the surfaces thereof, over layers containing, as a main component, a composition comprising 60 to 100 wt.% of a poly(lactic acid) and 40 to 0 wt.% of a biodegradable aliphatic polyester having a glass transition temperature (Tg) of 0 °C or lower, and in that the core layer and the over layer have crystallinity values {(ΔHm-ΔHc)/ΔHm} of 0.8 or more and 0.9 or more, respectively, which are calculated from the heat of melting of crystal (ΔHm) of the poly(lactic acid) part thereof observed in temperature rising and the heat of crystallization (ΔHc) of the poly(lactic acid) part thereof generating through crystallization during temperature lowering.
