ABSTRACT:
There is provided an IC card where a pair of, upper and lower metal panels are respectively fixed to the frame; edge portions of the metal panel are provided with bend portions; grooves each of which comprises a pair of uneven vertical walls having a plurality of depressions and projections extending in the direction of the width of the frame are provided on the top and bottom surfaces of the frame; the distance between the projections on both the uneven vertical walls in the direction of the width of the frame is set so as to be smaller than the thickness of the bend portions by a given amount; and the metal panel is fixed to the frame with the bend portions press-fitted into the grooves along the projections. The IC card is advantageous in the manufacturing cost and is capable of stably providing a fixing force sufficient to withstand a long-term use, with regard to the fixation of upper and lower panel members to a frame.
