The resonator includes a piezoelectric substrate laminated with dielectric substrates and external electrodes disposed on the laminate body. A plurality of external electrodes are arranged to extend from the outer major surface of the first dielectric substrate to the outer major surface of the second dielectric substrate along first and second side surfaces disposed opposite to each other. On the outer major surface of the second dielectric substrate, at least one external electrode is divided into first and second electrode portions.

摘要： A method of forming a groove on a mother material substrate includes the steps of forming a first layer on a surface of the mother material substrate, the first layer including a chain-polymer material which is soluble in an organic solvent. Then a second layer is formed on the first layer except for a portion where the groove is to be formed. The second layer includes a chain-polymer material having very high resistance to sand blasting. Then a groove is formed by cutting the first layer and the mother material substrate at the portion where the groove is to be formed, by a sand blasting process in which sand is directed from above the second layer downwardly. Then the first and second layers are removed from the mother material by dissolving the first layer using the organic solvent.
