PURPOSE: A ceramic resonator is provided to prevent nonuniform vibration of a vibration part by preventing eccentricity of lead frame fixed on Piezo electricity board. CONSTITUTION: A front oscillation part is connected with input-terminal on the one side, forming on upper part of front the Piezo electricity board(100). A backside oscillation part is connected output-terminal(140) symmetrically with input-terminal(130), forming correspondently to the front oscillation part. A front capacitor is connected with common terminal, forming on the lower part of the front oscillation part. a backside capacitor is symmetrically with the front capacitor, and forming with the same shape with front capacitor on the lower part of backside oscillation part. A side lead frame(230) is formed to connect each other with the input and output electrode. A center lead frame(250) is formed to connect with common electrode of the front or backside. |
