Summary: | PROBLEM TO BE SOLVED: To provide a grooved tuning fork type crystal resonator, of which the problem that a tuning fork arm is easily destroyed due to vibration and shocks, etc. due to problems in the mechanical strength of the tuning fork arm, since the thickness of a groove of the tuning fork arm is small, and since it is about half of the thickness near the outer side of the tuning fork arm, is solved and which is small in size, of high performance, high in shock resistance and low in price. SOLUTION: The tuning fork arms 2, 3 of the tuning fork type crystal resonator 1 have grooves 6 to 13, whose shapes of cross sections in thickness directions are almost V-shaped along longitudinal directions of front surfaces and rear surfaces.
