RESONATION DEVICE, OSCILLATOR, ELECTRONIC APPARATUS, AND MOVING OBJECT

摘要

A resonation device includes substrate, a resonation element that is attached to first main surface of substrate at first and second attachment portion, and heat-generating unit that is disposed on second main surface which is side opposite to first main surface so as to overlap with resonation element in a planar view. When an angle formed by line which connects center of resonation element and center of first attachment portion and virtual line which connects center of heat-generating unit and center of resonation element in a planar view is θ1 and an angle formed by a line which connects center of resonation element and center of second attachment portion and virtual line which connects center of heat-generating unit and center of resonation element in a planar view is θ2, conditions 0°<θ1<90°, 0°<θ2<90°, and 0°<|θ1−θ2|<10° are satisfied.

1. A resonation device comprising:
a substrate; a resonation element that is attached to a first main surface of the substrate at a first attachment portion and a second attachment portion; and a heat-generating unit that is disposed on a second main surface which is a side opposite to the first main surface so as to overlap with the resonation element in a planar view, wherein when an angle formed by a line which connects a center of the resonation element and a center of the first attachment portion and a virtual line which connects a center of the heat-generating unit and the center of the resonation element in a planar view is θ1 and an angle formed by a line which connects the center of the resonation element and a center of the second attachment portion and the virtual line which connects the center of the heat-generating unit and the center of the resonation element in a planar view is θ2, conditions 0°<θ1<90°, 0°<θ2<90°, and 0°<|θ1−θ2|<10° are satisfied.
