Vibrating Reed, Vibrator, Oscillator, And Electronic Device

Abstract: A vibrating reed capable of improving impact resistance is provided. A crystal vibrating reed is a vibrating reed formed by etching a Z plate which is cut at predetermined angles with respect to the crystal axes of a crystal. The crystal vibrating reed includes a base, a pair of vibrating arms extending from the base in the Y-axis direction, and a positive X-axis notch and a negative X-axis notch formed by notching the base in the X-axis direction. The positive X-axis notch is formed by notching the base from the negative side of the X axis towards the positive side so that the width of the positive X-axis notch increases as it approaches the outer circumference.
