To present both of vibration and heat feeling to a user.SOLUTION: A tactile presentation device includes at least one dielectric layer 20, a plurality of electrode layers 21 and 22 sandwiching the dielectric layer 20, and a DEA 12 having a first insulation layer 23 as a presentation layer which is stacked on the at least one electrode layer 21 for constituting an outer most layer, and a driving unit which applies a voltage between the electrode layers 21 and 22 sandwiching the dielectric layer 20. The dielectric layer 20 includes an expanding/contracting section 20A which expands/contracts by application of a voltage, and a heating section 20B which generates heat by applying a voltage. Vibration is presented to a user via the first insulation layer 23 by applying a low frequencies expansion/contraction voltage to between the electrode layers 21 and 22 sandwiching the expanding/contracting section 20A via the driving unit, while heat feeling is presented to the user via the first insulation layer 23 by applying a heat generation voltage having a higher frequency than the expansion/contraction voltage to between the electrode layers 21 and 22 sandwiching the heating section 20B.SELECTED DRAWING: Figure 2 【課題】使用者に振動及び熱感の双方を提示すること。【解決手段】触感提示装置は、少なくとも１つの誘電層２０、誘電層２０を挟む複数の電極層２１，２２、及び少なくとも１つの電極層２１に積層されて最外層を構成する提示層としての第１絶縁層２３を有するＤＥＡ１２と、誘電層２０を挟む電極層２１，２２間に電圧を印加する駆動部とを備えている。誘電層２０は、電圧の印加により伸縮する伸縮部２０Ａと、電圧の印加により発熱する発熱部２０Ｂとを有している。駆動部を通じて、伸縮部２０Ａを挟む電極層２１，２２間に対して低周波の伸縮電圧を印加することにより、第１絶縁層２３を介して使用者に振動を提示する一方、発熱部２０Ｂを挟む電極層２１，２２間に対して伸縮電圧よりも高周波の発熱電圧を印加することにより、第１絶縁層２３を介して使用者に熱感を提示する。【選択図】図２
