Claim:
1. A touch operation device comprising: a first piezoelectric layer having a piezoelectric property and flexibility; a second piezoelectric layer having a piezoelectric property and flexibility and disposed to correspond with the first piezoelectric layer; a touch detection layer positioned in a stacked arrangement between the first piezoelectric layer and the second piezoelectric layer piezoelectric layer and which is disposed to correspond with the first piezoelectric layer and the second piezoelectric layer, the touch detection layer detects a touch operation; and a piezoelectric body control circuit which selectively applies a signal to a part of the first piezoelectric layer and a corresponding part of the second piezoelectric layer corresponding to the touch operation detected by the touch detection layer and then bends the part of the first piezoelectric layer and the corresponding part of the second piezoelectric layer.
