Zusammenfassung:	[Object] To provide a magnetic detection device that detects magnetic fields in X, Y, and Z directions by forming magnetoresistive elements on inclined side surfaces of recesses formed in a substrate. [Solution] A Z detection unit 10 includes magnetoresistive elements 40 (R1, R2, R3, and R4) provided on inclined side surfaces 13 and 14 of Z detection recesses 11A and 11B. An X detection unit 20 includes magnetoresistive elements 40 (R5, R6, R7, and R8) provided on inclined side surfaces 23 and 24 of X detection recesses 21A and 21B. A Y detection unit 30 includes magnetoresistive elements 40 (R9, R10, R11, and R12) provided on inclined side surfaces 33 and 34 of Y detection recesses 31A and 31B. Directions of fixed magnetization (P) of fixed magnetic layers included in the magnetoresistive elements 40 are set to directions shown by arrows with solid lines.
