Claim:
1. A contact force sensor fabricated by machining a semiconductor material, the contact force sensor comprising: a first sensor configuration comprising a base part, a contact force transmission part formed in a direction orthogonal to the base part, and a first stress-electricity conversion element formed on a rear side of a forming surface of the base part, wherein the contact force transmission part is formed on the forming surface of the base part and the first stress-electricity conversion element converts a displacement of the contact force transmission part to an electrical signal; and a second sensor configuration comprising a coupling surface coupled to a rear side of the first sensor configuration, and a second stress-electricity conversion element being formed on the coupling surface, wherein the rear side of the first sensor configuration and the coupling surface of the second sensor configuration are coupled to sandwich a connection part of a first lead wire connected to the first stress-electricity conversion element and a connection part of a second lead wire connected to the second stress-electricity conversion element, and are arranged such that the first stress-electricity conversion element and the second stress-electricity conversion element formed respectively face each other.
