An optical disk device at least includes a housing, an optical pickup head, a circuit board, and a heat roof. The housing has a ventilating hole. The optical pickup head is disposed in the optical disk device for reading/writing the data on the disk. The circuit board is disposed in the housing. The heat roof is used for separating at least part of the circuit board from the optical pickup head. The heat roof includes a chamber in communication with the ventilating hole. The heat generated from at least part of the circuit board is within the chamber and then diffused to the outside of the optical disk device through the ventilating hole.
