振动片、振子、振荡器、电子设备以及移动体
摘要：
提供振动片、振子、振荡器、电子设备以及移动体，能够提高耐冲击性和Q值。在振动片(2)中，基部(4)包含第1基部(41)、第2基部(42)和连结部(43)，基部(4)包含设置于(43)的第1基部(41)侧的端部、且沿着X轴方向的宽度随着朝向第2基部(42)而连续减小的宽度缩小部(411)，俯视时宽度缩小部(411)的外缘和连结部(43)的外缘为不包含角部的连续的线，在设该曲线的第1基部(41)侧的部分的切线与平行于X轴方向的线段所成的角为θ时，满足0°＜θ＜90°的关系。
摘要（英）：

A resonator element, a resonator, an oscillator, an electronic device, and a moving object are provided. A base portion (4) includes a first base portion (41), a second base portion (42), and a connecting portion (43). The base portion (4) includes a width-decreasing portion (411) that is provided at an end of the connecting portion on the first base portion side and that has a width along an X-axis direction which continuously decreases toward the second base portion (42). An outer edge of the width-decreasing portion (411) and an outer edge of the connecting portion (43) form a continuous line that does not include a corner portion, when seen in a plan view. When an angle between a tangent of a portion of the curved line on the first base portion (41) side and a segment parallel to the X-axis direction is set to [theta], a relation of 0 DEG <[theta]<90 DEG is satisfied.
