Abstract
A piezoelectric resonator unit includes a piezoelectric substrate, first and second excitation electrodes, first and second connecting electrodes, and first and second exterior members. The first excitation electrode and first connecting electrode are disposed on a first main surface of the piezoelectric substrate and are electrically connected to each other. Similarly, the second excitation electrode and the second connecting electrode are disposed on a second main surface of the piezoelectric substrate and are electrically connected to each other. First and second exterior members bonded to the substrate with sealing members interposed. The first exterior member includes a first terminal portion formed in a shape that externally exposes at least part of the first connecting electrode. A first outer electrode covers the first terminal portion and the exposed portion of the first connecting electrode protruding from the first exterior member.
