Patent ID: 7864531

Claim:
An electronic device comprising: a flexible flat cable which is extended in a predetermined extending direction; a circuit chip having a first contact surface which makes a direct physical contact with an upper surface of the flexible flat cable, the first contact surface having a corner portion; a heat sink which is arranged on the circuit chip to make a thermal contact with the circuit chip, and which releases a heat of the circuit chip; and an elastic member which is arranged under a lower surface of the flexible flat cable at a position overlapping with the heat sink in a particular direction perpendicular to the lower surface of the flexible flat cable, wherein the upper surface of the flexible flat cable covers entirely the first contact surface of the circuit chip; and the elastic member does not overlap with the corner portion of the circuit chip, but overlaps with the circuit chip in the particular direction at an inner portion of the circuit chip located inside the corner portion, and the elastic member does not press the flexible flat cable against the corner portion of the circuit chip.
