Ic card and method of manufacturing the same

A memory card comprising:

• a substrate having a front surface and a rear surface,
• a flash memory chip mounted over the front surface of the substrate,
• a controller chip for the flash memory chip mounted over the front surface of the substrate,
• a plurality of external connection terminals arranged over the rear surface of the substrate,
• a first sealing portion covering the flash memory chip, the controller chip and at least a portion of the front surface of the substrate adjacent to one of the flash memory chip and the controller chip, and
• a case covering the first sealing portion,
• wherein a second sealing portion is formed over the rear surface of the substrate and covers the rear surface of the substrate such that the external connection terminals are exposed,
• wherein the first sealing portion is made of thermosetting resin material,
• wherein the case and the second sealing portion are made of thermoplastic resin material,
• wherein the second sealing portion has portions formed between adjacent ones of the external connection terminals, and
• wherein the memory card has a mechanically operated part externally accessible at a side-surface of the memory card.
