<p>[PROBLEMS] To provide a magnetic sensor and magnetic encoder in which down sizing is realized by improving the layout of terminals connected electrically with magnetoresistance effect elements in particular. [MEANS FOR SOLVING PROBLEMS] The magnetoresistance effect elements (24a to 24h) are arranged in matrix in a relative movement direction (direction X1) and in a vertical direction (direction Y1-Y2) orthogonal to the relative movement direction. One input terminal (52) and two ground terminals (66, 67) are provided. The input terminal (52), the ground terminal (66) and output terminals (50, 51, 54, 55) are respectively arranged in areas (70, 71, 72) among the respective magnetoresistance effect elements arranged side by side and spaced in the relative movement direction. The respective terminals and the respective magnetoresistance effect elements are connected electrically through wiring layers (shown by shading) to constitute two bridge circuits of A-phase and B-phase.</p> |
