Abstract:
A heat sink capable of dissipating heat concentrating on a chip portion of a power semiconductor device module efficiently is provided. A heat sink ( 20 ) includes a heat sink body ( 21 ) in which a power semiconductor device module ( 10 ) having a plurality of power semiconductor devices ( 11 ) is placed on a cooling surface F 1  and which radiates heat generated by the power semiconductor device ( 11 ); and a heat dissipation structure portion ( 25 ) having a higher heat conductivity than the heat sink body ( 21 ) and capable of dissipating heat generated by the power semiconductor device ( 11 ), wherein the heat dissipation structure portion ( 25 ) is provided at a position overlapping the power semiconductor device ( 11 ) disposed in the power semiconductor device module ( 10 ) in a direction (Z) orthogonal to the cooling surface (F 1 ) of the heat sink body ( 21 ).

Claim (Index 2):
The heat sink according to  claim 1 , wherein the heat dissipation structure portion is a heat dissipation sheet which is formed in a planar form using a metal material having a higher heat conductivity than the heat sink body and which is disposed in proximity to or on the power semiconductor device module in the heat sink body, and\n the heat dissipation sheet is disposed so as to overlap the power semiconductor device disposed in the power semiconductor device module in the direction orthogonal to the cooling surface of the heat sink body.
