An IC module including an integrated circuit chip and external connecting terminals connecting with the leads of the IC chip is accommodated in a cavity of a center sheet. First and second laminated structures, each of which is made of a plurality of sheets, are bonded to one and the other side surfaces of the center sheet. Each one of the first and second laminated structures has the same number of sheets and the same number of adhesive layers. Therefore, contraction and drawing forces produced by a change of environment and applied to the center sheet is counterbalanced, and warpage of the memory card is prevented.
