摘要：
振动元件、振子、振荡器、电子设备以及移动体。振动元件(2)包含振动片(3)，振动片(3)具有：基部(31)、振动臂(32)、连接部(34)以及连结基部(31)与连接部(34)的连结部(35)，在设振动片(3)的厚度为T、基部31的宽度为W1、连结部35的宽度为W2时，满足50μm≤T≤210μm、0.067≤W2/W1≤0.335的关系，在设振动臂(32)的臂部(321)的宽度为W3、锤头(322)的宽度为W4时，满足W4≥2.8W3的关系。
摘要（英）：

Resonator element, resonator, oscillator, electronic apparatus, and mobile object. The resonator element (2) includes a resonator blank (3) having a base portion (31), a vibrating arm (32), a linking portion (34), and a connecting portion (35) connects the base portion (31) and the linking portion (34) to each other, in which, when a thickness of the resonator blank (3) is set to T, a width of the base portion (31) is set to W1, and a width of the connecting portion (35) is set to W2, a relationship of 50 [mu]m<=T<=210 [mu]m is satisfied, and a relationship of 0.067<=W2/W1<=0.335 is satisfied, and in which, when a width of the arm section (321) of the vibrating arm (32) is set to W3, and a width of the hammer head (322) is set to W4, a relationship of W4>=2.8*W3 is satisfied.
