Abstract

PURPOSE:To form a chip type oscillator by providing an insulator base having a through-hole and a metallic terminal having a projection inserted to the said through-hole to a flat part of the terminal and soldering the said projection to a metallic layer provided around the through-hole of the insulator base. CONSTITUTION:The metallic terminal formed by spot-welding a projection 22 made of a short wire having 0.4mm. of diameter to a metallic thin plate 21 is inserted to a through-hole 12 of the insulator base 11 to form an air-tight base 51. The projection 22 is soldered to the metallic layer 13 provided around the through-hole 12. The metallic thin plate 21 forming the flat part is soldered to the metallic layer 15 of the lowr side of the base. A piezoelectric element 52 of tablet form is mounted on the air-tight base 51, and a metallic can 61 is sealed to it to obtain a chip type piezoelectric oscillator.
