<p>PROBLEM TO BE SOLVED: To provide an electric joint box having structure, which radiates effectively heat generated by a printed board containing a metal core, to the outside of a case. SOLUTION: A thermally conductive insulating sheet 24 is made to abut against at least a part of a printed board 21 containing a metal core, which is accommodated in a case and mounts electronic components. A metal spacer 25 is closely brought into contact with at least a part of the sheet 24. A heat- radiating means 30 is made to abut against the metal spacer 25. The thermally conductive insulating sheet 24 and the metal spacer 25 are formed, avoiding the protruding part of a lead terminal T of the printed board 21 containing a metal core.</p> |
