    • A strain detector which has a driven shaft for receiving a stress; a high magnetostrictive rate magnetic layer made of one of Co--B, Co--P, Co--Ni--B, Ni--Fe--P, and Co--Ni--P formed by electroless plating on the outer periphery of the driven shaft; and a detecting coil disposed through a gap on the periphery of the magnetic layer for detecting a variation in the permeability by a strain responsive to the stress of the magnetic layer, a method for manufacturing the strain detector which has the steps of forming a high magnetostrictive plating layer made of one of Co--B, Co--P, Co--Ni--B, Ni--Fe--P and Co--Ni--P by electroless plating on the periphery of the driven shaft; and selectively removing the plating layer to obtain a magnetic layer made of a plurality of magnetic pieces aligned in parallel at a predetermined angle with respect to the central axis of the driven shaft. Thus, the strain detector has high accuracy, high sensitivity and high reliability, and the method for manufacturing the strain detector can inexpensively manufacture the strain detector in good mass productivity.
