Abstract(in English)	In this paper, an equivalent circuit of the vibratory gyroscope utilizing a combination of the first mode of a longitudinal vibration and the second mode of a flexural vibration, is proposed. The distribution of Coriolis force dose not coinside with the detection mode in this structure. Because of this, a conventional equivalent circuit is not able to apply to a study of this structure. Thereupon, the circuit that can be applied to such structure has been hoped. A value of the coefficient K_ included in the gyrator constant, should be known, in the case that the derived equivalent circuit is used actually. This value was calculated here. As a result, it was clarified that K_=-0.1184 in the case of a slender bar. A characteristic of an angular rate sensor was simulated by using the circuit, and the result was compared with the measured one. Then, both result coinsided well.
