To obtain a method for printing on an electronic memory card wherein quality control in manufacturing cards is possible, printing work can be simplified, and looks of diagrams can be improved.

Into a mold 20 equipped with a cavity 23 which forms a shape of a card body, a thermoplastic material in a melted state is injected, and the melted material is coagulated in a state that an electronic module 43 exists in the mold so as to form an electronic memory card. The memory card is taken out from the mold and a diagram is printed on a main face which is at least a main face of the card body, has an electric contact on the same face, and includes a contact face 30 of the electronic module 3 excepting the electronic contact itself.
