Abstract
A subminiature flexural mode quartz crystal vibrator comprises a tuning fork formed by photolithographic techniques from a thin quartz crystal plate obtained by rotating an X-cut plate around the X-axis by an angle of 0.degree. to 10.degree. and further rotating the X-cut plate around the Y'-axis by an angle of 70.degree. to 90.degree., the plate having a thickness of less than 0.2 mm. Electrodes formed on sides of the tines are of a different metallic material from planar electrodes formed on at least one of the top and bottom surfaces of the tines. A side electrode of one tine is electrically connected by an overlapping joint with a planar electrode of the other tine.
