A heatsink arrangement attached to a semiconductor device includes: a first heatsink placed in close contact with the semiconductor device; and second heatsink placed in close contact with the first heatsink, wherein the first heatsink and the second heatsink are connected to a power supply circuit for the semiconductor device via first connector and second connector, respectively. Thus, the present invention provides a heatsink arrangement for a semiconductor device used in an electric/electronic circuit that radiates less high-frequency noise even when a large current flows through the semiconductor device and that provides a high heat-radiating efficiency.
