Abstract

PURPOSE:To obtain an inexpensive quartz oscillator less in secular change by applying an adhesive, cured at the normal temperatures, to fitted-in part where a base made of synthetic resin supporting a quartz oscillating far is fitted in a case made of synthetic resin, and by sealing the part with an adhesive cured by heat. CONSTITUTION:In a case 6 made of synthetic resin, a base 5' is pressed with a quartz oscillating far 1 inside. The base 5' enters the case 6 and is held temporarily. In this state, the 1st adhesive cured at the normal temperatures is applied to form the 1st layer 7, which is curved at the normal temperatures. In the formation of the layer 7, the adhesive may be applied only at the circmference of the fitted-in part B between the base 5' and case 6 instead of applying it over the entire surface of the bottom. Then, the 2nd adhesive capable of curing by heat is applied to form the 2nd layer 8, which is cured thermally. Thus, the adhesives superior in shock resistance for the layer 7 and in airtightness for the layer 8 are used in combination to perform sealing which is less in secular change and extremely stable at low cost.
