したことを特徴とする音叉型水晶振動子。In an XY-cut tuning fork type crystal resonator formed from a thin plate by etching, the shape of the slit is such that both legs of the tuning fork are formed due to the anisotropy of the progress of etching on the side surfaces of the thin plate. One width dimension is made wider than the other, and the length dimensions of both legs of the tuning fork are equal to each other, and the width dimension of the part of the leg with the thicker width dimension at the slit bottom excluding the slit bottom. A tuning fork type crystal resonator characterized by being formed thinner than the width of the corresponding part of the leg.
