A piezoelectric component which suppress ripples in the range of oscillation frequency and achieves stabilization of oscillation frequency is provided. A piezoelectric component of the invention includes a support substrate; a piezoelectric element having an elongated shape, comprising excitation electrodes disposed on one principal surface and the other principal surface thereof, respectively, the excitation electrodes facing each other; a first support portion and a second support portion which are disposed between both ends in a longitudinal direction of the piezoelectric element and the support substrate; and an electrically conductive joining material which joins the first support portion and the second support portion to the ends of the piezoelectric element, respectively. A center of the piezoelectric element is offset with respect to an intermediate point between the first support portion and the second support portion as seen in a plan view of the piezoelectric component.
