Abstract
Provided are multiple normal stress detection sensor units capable of detecting a normal stress, and a sheet layer portion. The sheet layer portion includes an exterior sheet layer portion, a force detection sheet layer portion incorporating normal stress detection units, and an intermediary layer sandwiched between the exterior sheet layer portion and the force detection sheet layer portion. The exterior sheet layer portion and the force detection sheet layer portion include multiple protrusions protruding in directions opposed to each other, and are disposed such that the protrusions engage each other with the intermediary layer interposed therebetween. Each normal stress detection sensor unit includes a central portion detection sensor device disposed immediately below a central portion of the protrusion provided on the force detection sheet portion, and at least two edge detection sensor devices disposed immediately below edge portions of the protrusion provided on the force detection sheet portion.
