PROBLEM TO BE SOLVED: To manufacture a heat sink excellent in heat dissipating property without using an expensive heat pipe or the like and provide it at a low cost, by a method wherein a heat sink has a hollow part formed by engaging two members, a corrugate fin which is formed of material excellent in thermal conductivity such as aluminum and copper and molded in a corrugate shape and whose thickness is at most 0.5 mm is put in the hollow part constituted of the two members, and the corrugate fin is bonded and brought into contact with the inside of the hollow part without using adhesive agent when the two members are engaged. SOLUTION: In this heat sink, a fin member which dissipates heat from a base and is slightly larger than a space of the hollow part and molded in a corrugate shape is put between a base member on which a heat generating element is to be mounted and a lid member which is engaged with the base member and forms the hollow part. The fin is fixed between the base member and the lid member simultaneously with engagement of the lid member with the base member and brought into contact with the base plate member and the lid member. As a result, heat is conducted from a surface of the base member to the fin member.
