The fan unit includes a fan, a unit housing, and a connector. The fan has a frame member and a motor supported to the frame member. The motor has a rotating shaft on which an impeller is mounted. The impeller is rotated by the motor to generate an air flow. The unit housing is integrally formed by resin molding. The unit housing is of a substantially rectangular parallelepiped box-shape having a front plate, a rear plate, a lower plate, a first side plate, a second side plate, and an upper opening. The unit housing has a recessed fan mounting portion having an upper opening inside the lower plate, for engagingly accommodating the fan. The lower plate has at its portion corresponding to a bottom surface of the fan mounting portion a ventilation opening for allowing pass of the air flow generated by the fan. The connector is provided for electrical connection with the electric device. The connector is mounted on the rear plate so that a part of the connector is exposed.
