Abstract
[Problem] To provide a tactile-variable molded article with seamlessly adjustable hardness, a switch having a seamless surface, and a method for manufacturing a tactile-variable molded article. [Solution] A tactile-variable molded article 10 has an outer skin material 21, a base material 23 disposed with a gap 22 between the base material and the outer skin material, and an elastically deformable elastic structure 30 disposed in the gap between the outer skin material and the base material and having a void 31 and a resin support body 32. The tactile-variable molded article 10 has a plurality of regions in which the volume occupancy rate occupied by the support body per unit volume of the elastic structure varies along the plane direction of the outer skin material and the elastic modulus in a direction intersecting the outer skin material varies at different positions in the plane direction.
