1. A tactile sense presentation apparatus, comprising:
a mounting portion mountable on a target object, wherein the mounting portion includes:
a surface material that includes a contact portion configured to be in contact with the target object,
wherein the contact portion is deformable; and
a variable-volume structure portion that includes an elastic material;
a pump unit that includes a flow path, wherein
the flow path is connected to the mounting portion,
the flow path is configured to feed a fluid to the mounting portion for deformation of the surface material, and
the variable-volume structure portion is configured to deform the surface material by reception of pressure of the fluid; and
a control unit configured to control a drive of the pump unit.
