<P>PROBLEM TO BE SOLVED: To provide a heat sink which can prevent displacement between the heat sink and a substrate from occurring by making stable pressing force act on a mounted electronic component in a temporary stop operation to the substrate. <P>SOLUTION: A heat sink comprises a flat plate part 2 radiating heat from a heating part of a substrate 50. The flat plate part 2 includes: substrate locking members 10 fixed to the substrate; and press locking members 20 pressing the flat plate part to the heating part of the substrate. The substrate locking member 10 has a positioning part protruding toward the substrate side to engage with the substrate and keeping an interval between the substrate and the flat plate part. The press locking member 20 includes: a pressing part 21 composed of a plate material having elasticity, brought into surface contact and fixed to the flat plate part 2; and a connection part 22 protruding toward the outside of an edge of the flat plate part 2 from the pressing part 21, formed so as to be bent toward the substrate side and inserted and locked to a through hole formed in the substrate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
