The tactile sensation providing device has a tactile sensation provider (20, 21, 22) that provides a tactile sensation by vibration and a stretchable/contractible sealing member (52) that seals a space (50) on the opposite side of a tactile sensation providing surface 20a of the tactile sensation provider. The sealing member (52) may stretch/contracts, according to vibration of the tactile sensation provider (20, 21, 22), to approach a state where the atmospheric pressure of the space (50) on the opposite side of the tactile sensation providing surface (20a) and the atmospheric pressure of the space outside the tactile sensation providing device are balanced to each other.
