Abstract
A small-sized load sensor unit including a pressure member, to which a pressing force is applied, a strain body which is fixed to the pressure member by a first fixing member, a strain measuring unit which is provided on the strain body and is configured to be deformed together with the strain body, a first restricting unit which restricts a pressing force applied to a substantially center portion of the pressure member such that the pressing force becomes a predetermined threshold value or less, and a second restricting unit which restricts the pressure member from moving by a predetermined amount or more when a pressing force of an excessive load is applied to an edge portion of the pressure member.
