Abstract:
A method of producing a chip-type piezoelectric resonator, comprising the steps of:providing a piezoelectric mother substrate in which a groove is to be formed:forming a first layer on a surface of the piezoelectric mother substrate, said first layer including a chain-polymer material which is soluble in an organic solvent;forming a second layer on said first layer except for a portion where said groove is to be formed, said second layer including a chain-polymer material having blast-resistancy;forming said groove by cutting said first layer and said piezoelectric mother substrate at the portion where said groove is to be formed, by performing a blast process; andremoving said first and second layers from said piezoelectric mother substrate by dissolving said first layer by applying the organic solvent thereto so as to produce the chip-type piezoelectric resonator.
