Vibrating electrodes are formed on the front and back sides of the piezoelectric substrate approximately at the center, and the electrode forming one capacitor formed on one side is connected to the vibrating electrode on the other side via a shorting electrode formed at the end of the piezoelectric substrate. and connect the electrode forming the other capacitor formed on the one side to the vibrating electrode on the same side, and further connect the common terminal connected to the common electrode and each electrode forming the capacitor. In a piezoelectric component with a built-in capacitor in which connected input/output terminals are drawn out from one end side of the piezoelectric substrate, the shorting electrode is formed at an end of the piezoelectric substrate opposite to the side from which each terminal is drawn out. The piezoelectric component with a built-in capacitor is characterized in that the vibrating electrode is formed in a horizontally long rectangular shape in a direction parallel to the end on the terminal extraction side.
