Strain gauge and multi-axis force sensor

A flexure body configured to be used in a detection of a load applied in a first direction with a first Wheatstone bridge circuit and a detection of a load applied in a second direction orthogonal to the first direction with a second Wheatstone bridge circuit, the flexure body comprising:

• a flexure member;
• and
• a circuit pattern provided on the flexure member,
• wherein the flexure member has a flexure area configured to be strained under the load from a detection object and an area different from the flexure area;
• the circuit pattern includes two pieces of first-direction strain sensitive elements configured to construct the first Wheatstone bridge circuit, two pieces of second-direction strain sensitive elements configured to construct the second Wheatstone bridge circuit, and at least one of a first-direction fixed resistance element configured to construct the first Wheatstone bridge circuit and a second-direction fixed resistance element configured to construct the second Wheatstone bridge circuit;
• the two pieces of first-direction strain sensitive elements, the two pieces of second-direction strain sensitive elements, and the at least one of the first-direction fixed resistance element and the second-direction fixed resistance element are formed of a same material;
• and
• the two pieces of first-direction strain sensitive elements and the two pieces of second-direction strain sensitive elements are provided in the flexure area, and the at least one of the first-direction fixed resistance element and the second-direction fixed resistance element is provided in the area different from the flexure area.
