PROBLEM TO BE SOLVED: To provide a piezoelectric oscillator capable of inhibiting the immersion of resins when mounting resins on a substrate to make a resin mold.SOLUTION: A piezoelectric oscillator includes: a piezoelectric transducer 100 having vibration terminals 126A to 126D on the outer bottom surface thereof; an electric component container having a recess for housing an electric component 138; wall part electrodes 136A to 136D formed on the top face of a wall part 132B; a conductive joint member 150 disposed between the vibration terminals 126A to 126D and the wall part electrodes 136A to 136D for coupling a piezoelectric transducer 110 and the electric component container 130. Seen from a direction perpendicular to the outer bottom surface of the piezoelectric oscillator 100, the vibration terminals 126A to 126D and the wall part electrodes 136A to 136D include an opposing region in which both are facing each other and a non-opposing region which is shifted from the opposing region. In each of the pairs of opposing regions adjacent to each other in the circumferential direction on the outer bottom surface, the non-opposing regions is provided between the pairs of opposing regions. 【課題】基板に実装して樹脂モールドをした場合に、樹脂の侵入を抑制できる圧電発振器を提供する。【解決手段】外底面に振動子端子１２６Ａ〜Ｄを有する圧電振動子１００と、電子部品１３８が収容された凹部を有する電子部品用容器１３０と、壁部１３２Ｂの上面に形成された壁部電極１３６Ａ〜Ｄと、振動子端子１２６Ａ〜Ｄと壁部電極１３６Ａ〜Ｄとの間に配置されて、圧電振動子１１０と電子部品用容器１３０とを接合する導電性接合材１５０と、を備え、圧電発振器１００の外底面に垂直な方向から見たとき、振動子端子１２６Ａ〜Ｄ及び壁部電極１３６Ａ〜Ｄは互いに対向する領域である対向領域と対向領域からはみ出した領域である非対向領域とを有し、前記外底面の周方向に隣接する全ての一対の前記対向領域において前記一対の前記対向領域の間に前記非対向領域を有する。【選択図】図１
