The multiple small protrusions 20 have an elongate shape in a planar view and are arranged at such locations as to form the respective sides of each of polygon such that there is formed the lattice pattern formed of the polygon. Each small protrusion 20 having an elongate shape is easily bent and deformed in the direction perpendicular to the longitudinal direction and is hard to bend and deform in the longitudinal direction. Therefore, the deformation manner at the time when each small protrusion 20 is elastically deformed becomes stable, and variations in the feel at the time when the small protrusions 20 are pressed with a finger or a hand are suppressed. The multiple small protrusions 20 that are formed so as to constitute the lattice pattern are arranged such that the longitudinal directions are offset from each other. Therefore, an appropriate stiff feel is obtained because the small protrusions 20 support each other. Therefore, it is possible to obtain a further excellent feel due to a combination of the appropriate stiff feel and the soft feel through elastic deformation of the small protrusions 20. |
