A control apparatus of an automatic transmission including a plurality of gear mechanisms, frictional elements, an oil pressure supply device which supplies an oil pressure for operating the frictional elements between an engaged state and a disengaged state and an oil pressure controller which controls an oil pressure for operating the plurality of frictional elements. The oil pressure controller determines a heat quantity absorbed by the plurality of frictional elements when the frictional elements are switched between the engaged state and the disengaged state, and changes an operation state before the frictional elements proceed to the engaged state or the disengaged state, in accordance with whether the frictional elements have absorbed a predetermined heat quantity.
