<p>An angular velocity of the present invention includes a resonator formed of a resonating member and a connecting member, a first base connected to the connecting member, a holding plate to hold the first base, a circuit board fixed onto the holding plate, an elastic body disposed on an end part of at least one selected from the holding plate and circuit board, a case housing the resonator, first base, holding plate, circuit board and elastic body and provided with an opening, and a second base put in place so as to close the opening of the case. The resonator has a short side and a long side. The resonator is located with the direction of the long side thereof arranged perpendicular to the second base, the elastic body is located between an end part of at least one selected from the holding plate and circuit board and the walls of the case, and at least one selected from the holding plate and circuit board is held by the case with an elastic pressure of the elastic body, thereby allowing the compression rate of the elastic body to be prevented from varying. As a result, an angular velocity sensor having stable output characteristics is realized. <IMAGE></p> |
