Abstract
A force sensor device 1, which is to be coupled to a first coupling counterpart 61 in a direction of a predetermined axis, includes: a sensor chip 110 that detects a moment around the predetermined axis; and a first coupling portion 40 including a first contact face 44, where the first contact face 44 is to face the first coupling counterpart 61 in the direction of the predetermined axis and is to contact the first coupling counterpart 61. An arithmetic average surface roughness Sa of the first contact face 44 is 3.0 or higher.
