PROBLEM TO BE SOLVED: To provide a surface-mounted oscillator capable of promoting miniaturization of the planar outer shape, making vibration characteristics satisfactory. SOLUTION: The crystal oscillator for surface mounting is composed by hermetically sealing a container, after providing a rectangular crystal piece and a circuit element including at least an IC chip side by side to the bottom face of a container body. A protrude is provided in the extending direction of the side from at least two corners of the crystal piece. At least an L-shaped space is formed to a space in between the side orthogonal to the protrude. A lead electrode is formed to at least two places in the protrude and fixed to the inner bottom face of the container body by a conductive material, and at least the IC chip is arranged in the L-shaped space.
