In a six-axis force sensor, each optical displacement sensor comprises an optical module to emit a light and a reflecting member to reflect the light back to the optical module, such that the optical axis of the light from the optical module is aligned to the axial direction of the six-axis force sensor, rather than to the radial direction. Consequently, the six-axis force sensor can be downsized in the radial direction.
