Abstract
This torque sensor includes: an outer circumferential part and an inner circumferential part that have an annular shape and are disposed concentrically with a gap therebetween in the radial direction thereof; a plurality of double-supported beam-like connecting beam parts that are disposed with gaps therebetween in the circumferential direction and connect the outer circumferential part and the inner circumferential part; and detecting parts that detect the torque applied about a central axis to the outer circumferential part and the inner circumferential part, wherein both side surfaces of the connecting beam parts in the circumferential direction have concave curved shapes the respective radii of curvature of which gradually increase from the inner circumferential surface of the outer circumferential part and the outer circumferential surface of the inner circumferential part toward the center in the length direction of the connecting beam parts when seen in the direction of the central axis.
