PROBLEM TO BE SOLVED: To provide a circuit-containing type plastic card having smooth surface and small unevenness of thickness. SOLUTION: In this card, an antenna coil 2 and an IC 3-containing component 4 are sandwiched between soft resin sheets 1 of soft vinyl chloride resin or amorphous polyester. Then, hard resin sheets 5 of hard vinyl chloride resin are superposed on surfaces of the sheets 1, heated, pressurized and laminated. Thus, resin flow of the sheet 1 can be prevented by the sheets 5 to thereby obtain the circuit-containing type plastic card having smooth surface and small unevenness of its thickness. |
