Abstract

A portable storage medium having an electronic component therein, includes a card-shape case for housing the electronic component. The card-shape case includes a metallic plate substantially surrounding the electronic component for withstanding substantial external forces. The card-shape case includes a cushioning member which has a greater flexibility than that of the metallic plate. The cushioning member is attached to the metallic plate for cushioning a portion of the card-shape case against external forces. A magnetic stripe is flexibly supported on the card-shape case for deforming a limited amount under the application of external forces to the magnetic stripe in response to the flexibility of the cushioning member.
