摘要： A quartz-crystal vibrating piece includes an element unit, excitation electrodes, and an extraction electrode. The element unit includes a vibrator, a first thick portion, and second thick portions. The vibrator has a quadrilateral shape in plan view, vibrates in a thickness-shear mode, and has a thickness t1. The first thick portion has a rectangular shape in plan view, has a short side connected to one side of the vibrator, extends in a first direction, and has a thickness t2 thicker than the thickness t1. The second thick portions are connected to both side surfaces of an end portion of the first thick portion in an opposite side of the vibrator. Each of the second thick portions extends along a second direction intersecting with the first direction and having a thickness t3 thicker than the thickness t1 and same as or different from the thickness t2.
