1. A tactile presentation panel that has a tactile presentation knob placed on an operation surface and presents a tactile sense to a user via the tactile presentation knob, the tactile presentation panel comprising:
a control circuit that divides the operation surface into a plurality of regions, assigns a control target to each of divided regions, and sets a tactile sense to be presented for each of the divided regions;
a tactile control circuit that generates a tactile sense set by the control circuit for each of the divided regions by changing a frictional force between the operation surface and the tactile presentation knob; and
a touch detection circuit that detects a position on the tactile presentation panel of the tactile presentation knob,
wherein the tactile presentation knob is placed in the divided region so that the control target is selected, and
the tactile presentation knob includes a conductive elastic portion being in contact with the operation surface and a rotation portion made up of a rigid body provided on the conductive elastic portion, and a tactile sense generated b a change of a frictional force generated between the operation surface and the conductive elastic portion is transmitted from the rotation portion to a user.
