A surface-mount crystal oscillator including a container body, a mounting terminal arranged on an outer bottom surface of the container body, a crystal blank hermetically sealed in said container body, and an IC chip having an oscillation circuit electrically connected to the crystal blank and hermetically sealed in the container body is mounted on a circuit board. A discrete part is arranged on the outer bottom surface of the container body, and the circuit board is provided with a connection terminal corresponding to the mounting terminal and an opening corresponding to the discrete part. The mounting terminal and the connection terminal are electrically and mechanically connected in a manner that the discrete part is accommodated in the opening, whereby the surface-mount crystal oscillator is surface-mounted on the circuit board.
