Abstract
PURPOSE:To make advance of a cutting edge smooth and to make sure of the connect ion between a conductive layer formed on the cutting plane and an electrode pattern by including small areas at intervals in which the electrode pattern is partially removed in the parts of the electrode pattern which corresponds to the track of the cutting edge. CONSTITUTION:As electrode patterns for a FM ceramic filter, a plurality of copper foil patterns 3-10 are formed on a pattern substrate 2. After one sheet of pattern substrate is stick on each of both sides of a piezoelectric substrate to form a base substrate, the base substrate is divided into 12 pieces (3X4) with a cutting edge. Small areas 41, 42 in which the respective electrode patterns are partially removed are formed at intervals in the parts of the electrode patterns 5, 7 which corresponds to the track of the cutting edge. Then, the cutting-off volume of the electrodes with the cutting edge is so decreased that the life of the cutting edge is increased. Therefore, the advance of the cutting edge becomes smooth, and the accuracy of cutting is increased. In the remaining patterns, since the side patterns thereof are exposed on the cutting planes, interconnection between conductive layers to be formed on the cutting planes and the electrode patterns are performed with reliability.
