摘要： A force detector capable of preventing short-circuit fault between electrodes and allowing for downsizing. A prescribed region encompasses a projection region defined by projecting a deformation region of a force sensor element, which is deformed when a force transmission member applies a force to the force sensor element, onto a base substrate. A plurality of terminals are provided by four soldering land electrodes formed, respectively, at four corners of the base substrate. The soldering land electrodes are shaped such that a portion of each soldering land electrode is located within the projection region to form a soldering portion.
