Abstract

PURPOSE:To secure the steady oscillation in terms of the aging along with the resistance secured to the impact given from any direction by fixing the upper end part of the crystal oscillator by the one-point system and with the elasticity secured and also supporting the lower end part by the two-point system and in the fusing way. CONSTITUTION:Crystal oscillator 1 features the shape obtained by giving the belt- type cross cutting to the convex semicylindrical shape, and contains electrodes 2 and 3 formed on both surfaces. Cushion piece 9 composed of the soft cushion material or the like is put between the upper end part of oacillator 1 and the linner top surface of metal cap 8. At the same time, the lower end part of oscillator 1 id suppurted by support substrate 4 made of the ceramic component. And concave part 5 functioning as the relief is provided at about the center of substrate 4, and metalized wiring parts 6a and 6b are provided at both sides of part 5. Then oscillator 1 is born in the fusing way onto the top surface of substrate 4 and at two areas of the both sides of part 5 via the heat pressure bonding means or the like.
