The present invention relates to a core sheet for card for forming a laminated card. The laminated card, which uses plant-derived plastics as raw materials, is eco-friendly and is excellent in heat resistance, impact resistance and adhesion between each layer (thermal adhesiveness). The core sheet for card according to the present invention is a core sheet for card (A) for use with a cover sheet (B) to form the laminated card. The cover sheet (B) has a constitution in which at least one layer is a layer constituted of an aromatic polyester based resin or a polycarbonate based resin or a mixed resin thereof as the main constituent resin. The core sheet for card is characterized by being obtained by laminating one layer or two layers or above, of which at least one layer is a lactic acid based resin layer constituted of a lactic acid based polymer as the main constituent resin. |
