PURPOSE:To obtain a package for piezoelectric resonator which can reduce the manufacturing processes and the cost with enhancement of the shock resistance, by fixing collectively the plural units of the piezoelectric resonator via the conductive adhesive and also connecting those resonators in parallel and electrically. CONSTITUTION:Plural units of piezoelectric resonator 16 the both end parts of which is held by concavities 111b and 111c is arranged 4 in plural units within case 11, and then cover 14 is fitted to the stepped area of the opening part of case 11 via the adhesive. In such way, each resonaotr 16 can be held and fixed at its both ends via holding stages 11b and 11c of case 11 plus holding bars 14a and 14b of cover 14 each. After this, conductive adhesive 17 is poured into channel parts 12a and 12b where the both ends of resonator 16 are positioned through holes 15a and 15b of cover 14 and then solidified to secure the collective fixture of both ends of plural units of resonator 16. At the same time, the lead wire draw-out electrode of each resonator 16 is connected to external lead wires 13a and 13b electrically via adhesive 17. After this, resin 18 is coated or poured to the opening surface of holes 15a and 15b each for solidification in order to secure the insulation to outside. |
