ABSTRACT:
An IC card includes a circuit board for mounting electronic parts, a frame surrounding the circuit board, and panel covering each of the front and back sides of the circuit board and the frame. Spacers serving as supporting members are adhered to the circuit board by soldering. Soldering can be performed by the same process as soldering electronic parts to the circuit board so as to prevent deformation of the panels and application of excessive force to the electronic parts even if an external force is applied to the panels.
