Disclosed are a magnetostrictive torque sensor and an electrical power steering device, wherein a first torque sensor (50A) has: one magnetostrictive film (80) provided on a steering shaft (22); a first coil (82a) and a second coil (82b) that detect changes in the magnetic characteristics of the magnetostrictive film (80); and a first housing (88a) that contains, at least, the steering shaft (22), the magnetostrictive film (80), the first coil (82a), and the second coil (82b). The first housing (88a) has a resin part (90), a cylindrical part (92) made of a metal that is soft magnetic, and a flange part (94) made of a metal that is soft magnetic. The resin part (90), the cylindrical part (92), and the flange part (94) are formed as a unit. |
