Abstract:
PROBLEM TO BE SOLVED: To solve the problem in which when mounting is performed beyond an uneven part by use of a flexible sheet including a conductive layer, the minimum curvature radius of the sheet prevents miniaturization of a mounting structure. SOLUTION: The connecting structure for electronic device includes a first surface including a first conductor, a second surface including a second conductor, an end of the first surface substantially parallel to Y axis, and a flexible sheet-like connecting body including a conductive layer. The end is taken as the origin of X coordinate, and the direction from the second surface to the first surface is taken as positive direction of Z coordinate. The first conductor and the sheet-like connecting body are electrically connected by a first connecting terminal, and the second conductor and the sheet-like connecting body are electrically connected by a second connecting terminal. The sheet-like connecting body has a form such that it extends from the first connecting terminal to the second connecting terminal across the end, wherein the Y component of the distance between a point where the Z coordinate of the sheet-like connecting body becomes smaller than the first surface first when advancing from the first connecting terminal to the second connecting terminal along the surface and the second connecting terminal is larger than the X-component of the distance between the end and the second connecting terminal.

Abstract:
PROBLEM TO BE SOLVED: To provide a small and lightweight electrical connection box which is excellent in recyclability and soaking/heat dissipation properties and is not restricted by the fixing position with low cost. SOLUTION: The electrical connection box 11 is constituted of a circuit board 14 mounting an electric component 23, and an upper case 12 and a lower case 13 covering the circuit board 14. A metal core substrate where the surface of a planar core 24 is covered with an insulation 25 is employed as the circuit board 14, and a heat sink 31 excellent in thermal conductivity is fixed to the vicinity of the electric component 23 while being connected with the metal core 24.
