A magnetostrictive stress sensor () includes: a magnetic member {, ()} having a magnetostriction; a permanent magnet () adjacent to the magnetic member; a magnetic sensor (A,B) for detecting a leak magnetic flux on a side opposite to the permanent magnet with respect to the magnetic member, wherein the leak magnetic flux changes according to a stress acting on the magnetic member and the magnetic sensor detects the change of the leak magnetic flux, to thereby detect the stress acting on the magnetic member, and a direction (A,A) of the stress acting on the magnetic member is substantially orthogonal to a magnetizing direction (A) of the permanent magnet.
