Abstract:
1. A piezoelectric vibrating piece, comprising: a vibrator, having a rectangular shape with a short side and a long side, the vibrator including excitation electrodes at both respective principal surfaces, the vibrator vibrating at a predetermined vibration frequency; a framing portion, surrounding a circumference of the vibrator; one connecting portion, connecting the vibrator and the framing portion; a first extraction electrode, being extracted from the excitation electrode formed on one principal surface to the framing portion via one principal surface of the connecting portion; and a second extraction electrode, being extracted from the extraction electrode formed on another principal surface to the framing portion via another principal surface of the connecting portion, a side surface of the connecting portion, and the one principal surface of the connecting portion, wherein a distance between a first side and a second side at the framing portion is larger than a distance between the first side and the second side at the connecting portion, the first side is a side of the first extraction electrode at the second extraction electrode side, the first side being from the connecting portion to the framing portion on the one principal surface, and the second side is a side of the second extraction electrode at the first extraction electrode side, the second side being from the connecting portion to the framing portion on the one principal surface.
