Abstract:
1. A method for manufacturing a load sensor including a load detection element and a support element, wherein the support element includes a base for mounting the load detection element on one side of the base and a spring for applying a preliminary load on the load detection element, wherein the spring includes a support portion for sandwiching the load detection element between the one side of the base and the support portion, a connection portion bonding to the base, and a connecting member for coupling the support portion and the connection portion, and wherein the support element transmits a detection load to the load detection element via the base and the spring, the method comprising: sandwiching the load detection element between the base and the spring; bonding the connection portion of the spring on the base so that the connecting member of the spring is deformed beyond the elastic deformation region to reach the plastic deformation region; pressing the support portion so that a contact surface of the support portion is plastically deformed, wherein the contact surface contacts the load detection element; and returning deformation of the connecting member to be in the elastic deformation region.
