1. A haptic presentation apparatus, comprising:
a first deformable layer on a front surface side;
a second deformable layer that is inward of the first deformable layer; and
a drive unit configured to control outflow and inflow of fluid between a first space and a second space, wherein
the first space retaining the fluid between the first deformable layer and the second deformable layer,
the second space retaining the fluid inward of the second deformable layer, and
a plurality of properties of the fluid flowing in and out of the first space are different from a plurality of properties of the fluid flowing in and out of the second space.
