Claim:
1. A crystal device comprising: a crystal blank which has a substantially block shape, a first excitation electrode part which is provided on an upper surface of the crystal blank, a first wiring part which extends from the first excitation electrode part up to an edge part of the upper surface of the crystal blank, a first lead-out terminal which is provided at the edge part of the upper surface of the crystal blank so as to be connected to the first wiring part, a first mounting terminal which is provided at a position facing the first lead-out terminal on a lower surface of the crystal blank, a first connection part which is provided so that one end is superimposed on the first lead-out terminal and the other end is superimposed on the first mounting terminal, a second excitation electrode part which is provided on the lower surface of the crystal blank, a second wiring part which extends from the second excitation electrode part up to an edge part of the lower surface of the crystal blank, a second lead-out terminal which is provided at the edge part of the lower surface of the crystal blank so as to be connected to the second wiring part, a substrate which has an upper surface provided with a first mounting pad and a second mounting pad, conductive adhesives which are provided between the first mounting pad and the first mounting terminal and between the second mounting pad and the second lead-out terminal, and a lid which is bonded to the upper surface of the substrate.
