摘要： The present invention relates to a crystal unit in which rectangular excitation electrodes are formed on two main surfaces of a rectangular crystal piece, an extracting electrode extends from at least one corner portion at each of two end portions from each of the excitation electrodes, and one of the corner portions of the crystal piece from which each extracting electrode extends is affixed by an electrically conductive adhesive to a step portion of the board, wherein a cutaway portion is provided in a corner portion of each of the excitation electrodes corresponding to one corner portion of the crystal piece, to increase the distance from the corner portion of the crystal piece, and the cutaway portion is formed as either a straight line or a curve. This provides a crystal unit in which contact between the excitation electrodes of the crystal piece and the electrically conductive adhesive is prevented, enabling reliable resonance.
