The present invention reduces measurement time. A gyroscope of the present invention includes a planar ion trap part, a microwave irradiation part, a laser irradiation part and a measurement part. The planar ion trap part includes two rf electrodes and two DC electrode rows, and forms ion traps that trap one ion on a substrate, a normal direction of the surface of the planar ion trap part corresponds to a z direction. The rf electrodes are disposed in the x direction on the substrate at a predetermined interval. The DC electrode rows are disposed in the x direction on the substrate so as to sandwich the two rf electrodes. The DC electrode rows each include at least five DC electrodes in the x direction. The trapped ions are spaced so as not to interfere with each other. The microwave irradiation part irradiates the ions with &#x3c0;/2 microwave pulses.
