PROBLEM TO BE SOLVED: To mount a heat sink to an electronic component side in a press state without carrying out screwing work. SOLUTION: An elastic piece 3 7 is formed in one piece on a terminal block 7 for retaining a terminal pin 6. As a result, utilizing the elastic piece 37 on the terminal block 7 allows the end section of the heat sink 9 to be mounted while the end section is being retained without carrying out the screwing work. At this time, the heat sink 9 is pressed to the side of the heat generation component 3 by engaging to the elastic piece 37, thus securely conducting heat from the heat generation component 3 to the heat sink 9.
