Abstract
An inventive temperature-compensated crystal oscillator has a construction such that a crystal oscillator element () is accommodated in a container () and an IC element () for controlling an oscillation output on the basis of the oscillation of the crystal oscillator element () is mounted on a lower surface of the container (). A plurality of electrode pads () at least including plural crystal electrode pads connected to the crystal oscillator element (), plural writing control electrode pads, and an oscillation output electrode pad, a ground electrode pad, a power source voltage electrode pad and an oscillation control electrode pad connected to surface mounting external terminals are arranged in a matrix configuration of m rows×n columns (wherein m and n are natural numbers not smaller than 2) in an IC element mounting area. The IC element () is electrically connected to the electrode pads (). The temperature-compensated crystal oscillator is excellent in IC element bonding reliability, and meets the need for the size reduction of the entire structure.
