摘要： PROBLEM TO BE SOLVED: To provide a magnetostrictive stress sensor which is excellent in an installing property to a detection target and detection sensitivity, compact and easy to be handled, and inexpensive and excellent in robustness, by putting a stress sensor using an opposite effect of magnetostriction to practical use. SOLUTION: A shaft-shaped magnetic body 1 having magnetostriction and equipped with a hollow portion 1a at a shaft core portion is magnetized in a circumferential direction to make a stress detecting portion 2. The stress detecting portion 2 is provided with a detection head 10 having a platy permanent magnet 11, magnetic sensors 12 and 13, and a platy yoke 14. Those sensors, magnet, and yoke are arranged at predetermined positions. The changes of a magnetic flux flowing outside the magnetic body when stress acts on the magnetic body 1, out of a magnetic flux generated from the permanent magnet 11 and distributed into a magnetic flux passing through the inside of the magnetic body 1 and flowing outside the magnetic body 1, is detected to detect axial stress acting on the magnetic body 1.
