Abstract
An operation support device that is placed on a touch panel detecting a change in electrostatic capacitance or a change in a contact region, includes: a case part; a first member attached inside the case part; a first deforming member that is an elastic member provided on an end of the first member and is provided between the first member and the touch panel; and a wall part that is attached inside the case part and sets a direction of deformation of the first deforming member when the case part approaches the touch panel, to a predetermined direction. As the case part approaches the touch panel, the electrostatic capacitance in a region facing the first defaming member increases due to defamation of the first deforming member or area of the contact region of the first defaming member increases due to deformation of the first defaming member.
