PROBLEM TO BE SOLVED: To obtain a piezoelectric resonance component, having a multilayered ceramic substrate that is superior in reliability of electrical connection between internal electrodes and electrodes used for outside connection and has a built-in capacitor. SOLUTION: This piezoelectric resonance component is provided with a multilayered ceramic substrate 2, having a structure in which first and second internal electrodes 5 and 6 are superimposed upon another through a capacitance payer 7 for constituting a capacitor and an electronic component element mounted on the substrate 2. The electronic component element is electrically connected to the internal electrode 5 and the electrode 5 is electrically connected to a connection electrode 21 on one side face 2a of the substrate 2. The connection electrode 21 is formed so that the electrode 21 is exposed on the side face 2a and is formed larger in thickness than that of the internal electrode 5. The component is electrically connected to the outside or an external electrode through the connecting electrode 21. COPYRIGHT: (C)2003,JPO
