A sheet-like miniaturized electronic device includes an electronic component assembly with a wiring base having switch contacts and a semiconductor IC chip operated by signals from the switch contacts. A display panel displays data according to signals from the semiconductor IC chip, and a battery supplies a drive voltage to the semiconductor IC chip. The wiring base, display panel and battery are electrically connected to one another and arranged in the same plane. An upper cover is provided in close contact with the upper side of the electronic component assembly, and has an operating section and a transparent display window. A lower cover is provided through an adhesive layer to the underside of the electronic component assembly.

A flat miniaturized electronic device comprising: a flat and thin insulating sheet with a conductive wiring pattern thereon; an electronic component coupled to said conductive wiring pattern, said electronic component having one end surface in the same plane as a first face of said insulating sheet

A flat miniaturized electronic device comprising: a flat and thin insulating sheet with a conductive wiring pattern thereon; an electronic component coupled to said conductive wiring pattern, said electronic component having one end surface in the same plane as a first face of said insulating sheet with its opposite end surface projecting from the plane of a second face of said insulating sheet opposite to said first face; a first cover mounted opposite to the first face of said insulating sheet and having key indicia thereon; switch means between said first cover and the first face of said insulating sheet for actuating an electrical connection to said conductive wiring pattern upon contact of said key indicia by an operator; a second cover having a flat outer surface and the same periphery as said first cover and mounted opposite to the second face of said insulating sheet so as to form a gap between the second cover and, respectively, the second face of said insulating sheet and the projecting end surface of said electronic component; and an adhesive layer filling said gap.
