Abstract: Numerous fine projections (20) are formed interspersed on a plate-shape member (18), and the neutral plane (S) of each fine projection (20) is inclined at an inclination angle ? to the normal line (O) such that the contact center (Q) does not overlap with the base part in the plane direction of the surface (22), so when a pressing load (F) is applied, the moment acting on the fine projections (20) is large, and the fine projections (20) easily deform to bend in the respective inclination direction. By this means, the tactile softness (cushion properties) are improved by preventing the fine projections (20) from undergoing simple compression deformation in the axial direction, and stick-slip due to friction between the fine projections (20) and the surface (22) is avoided, making it possible to obtain a smooth and stable tactile softness.
