Abstract
A resonator device includes: a resonator element that has a first surface on which a first mount electrode and a second mount electrode are disposed, and a second surface; a base that has a third surface which faces the first surface of the resonator element and on which a first base electrode and a second base electrode are disposed; a lid that has a fourth surface which faces the second surface of the resonator element; a first metal bump by which the first mount electrode and the first base electrode are bonded; a second metal bump by which the second mount electrode and the second base electrode are bonded; and a bonding member by which the second surface and the fourth surface are bonded. A loss tangent of the bonding member is larger than a loss tangent of the first metal bump and the second metal bump.
