ABSTRACT:
A quartz oscillator comprises a quartz blank having electrode films deposited on opposite parallel faces thereof. Holding wires which are parallel to the quartz blank extend along and spaced slightly from the opposite faces of the blank and are locally soldered to the quartz blank. The holding wires extend beyond the edge of the quartz blank and are secured to a holding substrate provided with electrical connections. The quartz oscillator is prepared by positioning a quartz blank and a holding substrate in a supporting frame, opposite faces of the quartz blank and holding substrate being provided at selected positions with solder parts. The holding wires are then positioned along opposite faces of the quartz blank and holding substrate and the solder parts are temporarily fused by radiant heat to bond the holding wires to the quartz blank and the holding substrate.
