Abstract
A groove (21) is formed on an upper surface of sealing resin (2) in the form of a strip. A device (101) is pressed against a flat surface of a radiating fin (55) by a band plate shaped clamper (61) which is engaged with the groove (21). Due to the engagement of the clamper (61) and the groove (21), movement of the device (101) is limited. Namely, the device (101) is stably fixed to the radiating fin (55). Since the device (101) is fixed to the radiating fin (55) by the clamper (61), no hole for receiving a fastening screw is provided in the sealing resin (2). Therefore, the sealing resin (2) is reduced, whereby miniaturization of the device (101) is implemented. Thus, the device is miniaturized at no sacrifice of radiation efficiency.
