Abstract: The present invention has an object of providing a motor drive device provided with a cooling mechanism by way of a fan motor, which is capable of also cooling separate elements in the surroundings of a heat generating element due to further improving the cooling function. The motor drive device is equipped with a fan motor, and a heat sink which cools the heat generating element on a printed substrate by way of exchanging heat with the heat generating element, in which the heat sink includes a main body of cylindrical shape fixed to the heat generating element, and having an air duct through which cooling airflow flows, and a communication hole that communicates from an exposed outer circumferential face of the main body to the air duct, and in which the fan motor generates cooling airflow that flows through the air duct.
