Abstract

A cooling apparatus for a heat-generating element includes: a heat sink on which the heat-generating element is mounted; a cooling component having a recess, the cooling component and the heat sink being faced and joined to each other so that the recess forms a coolant passage; and a sealing member provided between the heat sink and the cooling component so as to seal the coolant passage and separate an interior and exterior of the coolant passage. A first distance is longer than a second distance with regard to a distance between facing surfaces of the heat sink and the cooling component near the sealing member, the first distance being between the facing surfaces at an interior side of the coolant passage separated by the sealing member, and the second distance is a distance between the facing surfaces at an exterior side of the coolant passage separated by the sealing member.
