PROBLEM TO BE SOLVED: To provide an attitude angle detecting device having a gyroscope, an acceleration sensor and a magnetic sensor which is small-sized and easy to manufacture with a simple structure, and reduced in noise to perform a precise detection. SOLUTION: A flexible substrate 10 having three oscillators 21, 22, 23 mounted on the flat state is folded and installed to a processing circuit board so that the three oscillators 21, 22, 23 are mutually vertically arranged. Slits 14, 15 are formed each between the oscillators 21, 22, 23 on the flexible substrate 10 to interrupt or reduce the propagation of vibration, so that the difference each between natural resonance frequencies of the oscillators is set so as to be higher than the frequency band to be measured, or the frequency higher than the frequency band or more is removed by a low pass filter, whereby an attitude angle detecting device prevented from noise is provided. |
