In a hydraulic control device for an automatic transmission, which has a friction element that is released at a speed (a natural number) and an accumulator that alleviates changes in the oil pressure supplied to the friction element, an oil path that supplies back pressure to the accumulator is provided. A switching valve is provided, and the switching valve is configured to supply the above-mentioned back pressure to the accumulator during the first speed, and to stop supplying the above-mentioned back pressure to the accumulator during the m-th speed. Hydraulic control device for automatic transmission.
