<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive electronic circuit device that surely dissipates heat generated by an electronic component to the outside of a storage box and has high reliability with respect to heat generation of the electronic component and changes or the like in the ambient temperature of the storage box while having excellent assembly workability. <P>SOLUTION: The electronic circuit device is configured as follows. A heat sink 25 for dissipating heat of a semiconductor element 29 and an aluminum plate 37 being an outer shell of a storage box 1 are made thermally conductive to each other via an insulating sheet 49 and a thermally-conductive rubber member 60. The thermally-conductive rubber member 60 is compressed by the aluminum plate 37. The heat generated by the semiconductor element 29 is dissipated to the outside of the storage box 1, thereby improving reliability while improving assembly workability. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
