PURPOSE:To prevent the production of defective oscillation at a drop test and of cracks in using a thick crystal chip by adhering a metallic electrode of a crystal resonator provided to a crystal chip and an external lead conductor by a conductive adhesives including an epoxy resin, polybutadiene group liquid resin, petroleum group resin and conductive powder. CONSTITUTION:The conductive adhesives includes the epoxy resin, polybutadiene group liquid resin, petroleum group resin and conductive powder. Each component is kneaded by three-roll or the like to manufacture an adhesives. In applying dispense coating the conductive adhesives between the electrode of crystal chip and the pad of the lead conductor, the result is heated and cured for 30min at 150 deg.C to adhere both and the crystal resonator is manufactured with other assembling.
