An electronic component cooling apparatus capable of firmly mounting a fan unit mounting frame on a heat sink without increasing mechanical strength of the fan unit mounting frame. The fan unit mounting frame includes a pair of mounting legs provided thereon with hooks, which are engaged with hook engagements provided on a base of the heat sink. A top plate of the fan unit mounting frame is provided thereon with projections acting as a first pivotal movement preventing engagement structure and fitted in gaps defined between adjacent radiation fins of a radiation fin unit. Also, the top plate is provided thereon with projections which are abutted against end surfaces of the radiation fins positioned in a second direction, to thereby act as a second pivotal movement preventing engagement structure for preventing pivotal movement of the top plate in the second direction.
