To form first and second channel sensors by winding a winding around each projection magnetic pole formed on both sides of the first core body, and by providing the second core body having each ridged/grooved part on both sides of the first core body.
This linear sensor includes the first core body 1 having a plurality of first and second projected magnetic poles 2, 2A projecting to both sides; the second core body 6 disposed corresponding to the first core body 1; and the first and second ridged and grooved parts 7, 7A formed on each inner wall 6a, 6b of the second core body 6, in correspondence with the first and second projection magnetic poles 2, 2A. The linear sensor has a constitution wherein the first channel sensor 20 is formed on the side of each first projected magnetic pole 2, and the second channel sensor 30 is formed on the side of the second projected magnetic pole 2A.
