Abstract
A heat sink that radiates n exoergic circuit elements mounted on a circuit board includes a housing that has a heat-receiving surface that receives heat from the n exoergic circuit elements, and n+2 fixture parts to each of which a fixture member is attachable, each fixture member compressively fixing the housing onto the circuit board, wherein n is equal to or greater than 2, the heat sink is used to commonly radiate the n exoergic circuit elements, and a line that connects two fixture members to each other among n+2 fixture members passes between two centers of gravity of two adjacent exoergic circuit elements.
