Force detection device

A force detection device comprising:

• a substrate;
• and
• a force transmission block, wherein:
• the substrate includes:
• a mesa gauge arranged on a principal plane of the substrate and providing a bridge circuit;
• a connection region arranged on the principal plane and doped with an impurity;
• and
• a sealing portion arranged on the principal plane, surrounding all around the mesa gauge, and connected to the force transmission block;
• the mesa gauge includes:
• a first mesa gauge extending in a first direction;
• and
• a second mesa gauge extending in a second direction different from the first direction and spaced apart from the first mesa gauge;
• and
• the connection region is disposed between one end of the first mesa gauge and one end of the second mesa gauge, and electrically connects the one end of the first mesa gauge and the one end of the second mesa gauge.
