PROBLEM TO BE SOLVED: To provide a small integrated azimuth sensor capable of detection of azimuth and posture and loading on portable apparatuses. SOLUTION: The invention comprises an acceleration sensor 3 detecting gravitational acceleration, magnetic sensor 4 detecting geomagnetism and an operation processor 6 operating and processing the acceleration information from the acceleration sensor 3 and magnetism information from the magnetic sensor 4. The acceleration sensor 3 is constituted of a support body 8 fixed to a glass stage 5, a bob part 7, beams 31 to 38 movably supporting the bob part 7 to the support body 8 and the like. At a specific position of the bob part 7 constituting the acceleration sensor 3, the magnetic sensor 4 and the operation processor 6 are placed. By assembling the magnetic sensor 4 and the operation processor 6 in a part of the bob part 7 constituting the acceleration sensor 3, in this manner, total small-sizing is attained.
