| description | To provide a piezoelectric transducer capable of securing a measurement accuracy of an oscillatory frequency and an oscillator.SOLUTION: A piezoelectric transducer 10 comprises: a package 2 having a chip mounting region 40; and a piezoelectric vibration piece. The chip mounting region 40 has a shape having a long direction L and a short direction W. In the chip mounting region 40, motor terminals 41 and 42, chip electrodes 61 to 66, and connection wirings 71 to 76 are formed. Each of the monitor terminals 41 and 42 is provided so that a position is different to the long direction L. Each of side edges 41a and 42a of the monitor terminals 41 and 42 is opposite to each connection wiring. When comparing a first half region 40A and a second half region 40B which become a center shaft o1 of the chip mounting region 40, a total area of the chip electrode in the first half region 40A and each connection wiring is smaller than a total area of the chip electrode in the second half region 40B and each connection wiring. A center of gravity of at least one of the monitor terminals 41 and 42 is in the first half region 40A.SELECTED DRAWING: Figure 5
【課題】発振周波数の測定精度を確保できる圧電振動子および発振器を提供する。【解決手段】圧電振動子１０は、チップ実装領域４０を有するパッケージ２と、圧電振動片と、を備える。チップ実装領域４０は、長手方向Ｌと短手方向Ｗとを有する形状とされる。チップ実装領域４０に、モニター端子４１，４２と、チップ用電極６１～６６と、接続配線７１～７６と、が形成されている。モニター端子４１，４２は、長手方向Ｌに位置を違えて設けられる。モニター端子４１，４２の側縁４１ａ，４２ａは、それぞれ前記接続配線と対向する。チップ実装領域４０の中央軸Ｏ１を境界とする第１半領域４０Ａと第２半領域４０Ｂとを対比すると、第１半領域４０Ａにおけるチップ用電極および接続配線の合計面積は、第２半領域４０Ｂにおけるチップ用電極および接続配線の合計面積より小さい。モニター端子４１，４２のうち少なくとも一方は、重心が第１半領域４０Ａにある。【選択図】図５ |
