PROBLEM TO BE SOLVED: To provide a heat sink retaining clip excellent in operativity which can flexibly correspond to the variation of a heat sink size, LSI load resistance, a substrate thickness or the like, stably retain the heat sink without causing come-off from a substrate and reduce a manufacturing cost by a relatively simple structure. SOLUTION: The clip has elastic locking parts 4a, 4b with spring properties at both ends. Locking is carried out by inserting the elastic locking parts into holes formed in a substrate by using a spring property. An extendable part 6 is formed between the elastic locking parts at both ends, and the length can be adjusted by the extendable part. Each elastic locking part is constituted of a pair of clicks 7c, 7d with spring properties. Since the length can be adjusted by the extendable part, it is possible to flexibly correspond to various heat sink sizes and to meet the variation of an LSI withstand load and a substrate thickness or the like, as the elastic locking parts at both ends can be locked to the receiving part of the substrate using its spring property, thus stably retaining the heat sink without causing come-off from the substrate.
