Abstract
Piezo-electric assembly having a piezo-electric resonator of trapped energy type assembled within a forming case. A bulkhead within the case prevents manufacturing defects due to internal spreading of conductive paste, regardless of variations in the coating amount of the conductive paste in mass production or variations in the mount pressure. Constant clearance exists between the internal connecting portions of the external terminals and the draw-out electrode (input/output) electrodes of the resonator, so that any variation in the conductive paste coating amount or the mount pressure is compensated.
