    摘要： A piezoelectric vibrator that includes a piezoelectric resonator, a substrate having opposite first and second principal surfaces, and an electrically conductive holding member holding the piezoelectric resonator on the first principal surface of the substrate such that the piezoelectric resonator is able to be excited. The electrically conductive holding member contains a first filler containing an electrically conductive material as a main component and a second filler containing an electrically insulating material as a main component and having a smaller Young's modulus than the first filler. In a plan view in a direction normal to the first principal surface of the substrate, the second filler is more densely disposed in an outer peripheral region of the electrically conductive holding member than in a central region of the electrically conductive holding member.

    摘要： A piezoelectric device is provided and includes: a piezoelectric vibrating piece, having an outer shape in rectangular shape and including an excitation electrode formed on both principal surfaces which are a top surface and a lower surface, an electrode pad formed at both ends of one short side, and an extraction electrode extracted from the excitation electrode to the electrode pad to be electrically connected to the electrode pad; a package, including a placement surface on which the piezoelectric vibrating piece is placed as opposed to the lower surface of the piezoelectric vibrating piece, and an adhesion pad formed on the placement surface; and a conductive adhesive, securing the piezoelectric vibrating piece to the package and electrically connecting the adhesion pad to the electrode pad. An adhesive is applied on the top surface of the piezoelectric vibrating piece and between the conductive adhesive and the excitation electrode.

    摘要： A piezoelectric component in which leakage of vibration is suppressed and vibration characteristics are excellent is provided. A piezoelectric component of the invention includes a support substrate; and a piezoelectric element mounted on the support substrate. The piezoelectric element includes electrodes (vibration electrodes) on one main surface and the other main surface of the piezoelectric element so that the electrodes have an area facing each other, and a concave area extending in a width direction of the piezoelectric element, in at least one of excepted areas which are areas other than the electrodes facing each other of the one main surface and the other main surface. At least part of corner portions of the concave area which extend in the width direction forms a curved surface.
