A fan motor, which is mounted on an upper surface of an electronic component to cool the electronic component. The fan motor includes a fan motor and a thermally dissipating surface to which the fan motor is fixed. The fan motor includes a motor portion having cooling blades and an attaching plate having leg portions formed in its peripheral portions to fix the motor portion to the thermally dissipating surface. The thermally dissipating surface has a hole portion substantially as large as the attaching plate, and recessed portions capable of accommodating at least the leg portion therein. The attaching plate is passed through the hole portion toward the rear surface side and is rotated so that the leg portions are accommodated in the recessed portions.
