A driving apparatus which electrically drives a component built in an industrial instrument, comprises a housing including a supply inlet and an exhaust outlet, a fan configured to form an air current so that air is taken into the housing through the supply inlet and exhausted from inside the housing through the exhaust outlet, a driving circuit block which is accommodated in the housing so as to be cooled by the air current, and configured to electrically drive the component, and a cooling unit configured to regulate a temperature of the air exhausted from inside the housing through the exhaust outlet so as to decrease a temperature difference between the air taken into the housing through the supply inlet and the air exhausted from inside the housing through the exhaust outlet.
