Abstract:
1. A resonating element comprising: a base substrate that has first and second base terminals; a resonator element that includes a vibrating portion; first and second excitation electrodes that are respectively formed on lower and upper surfaces of the vibrating portion; an intermediate substrate in which the resonator element is mounted so as to be spaced from the first and second excitation electrodes, the intermediate substrate being mounted to the base substrate, the intermediate substrate being spaced apart from the base substrate; and a spiral electrode pattern that is provided on the intermediate substrate and that has first and second ends, wherein the first base terminal, the first excitation electrode, and the first and second ends of the spiral electrode pattern are electrically connected to each other, the second base terminal and the second excitation electrode are electrically connected to each other.
