Abstract
A soft magnetic component for a torque sensor, formed by resin-molding a soft magnetic material that contains Ni, Fe in such an amount that Fe/(Fe+Ni) is within a range from 10.0% to 16.0% in terms of mass ratio, and 3.5% by mass to 7.5% by mass of M (the M represents one or more elements selected from among Mo, Nb, Cr, Cu, Ti, and W) and has a saturation magnetostriction of at least −4.0 ppm and less than 0 ppm, is provided.
