Abstract
Provided are an oven controlled crystal oscillator in which in a case where a metal lead is soldered to a substrate, even if cracks occur in the solder, its reliability is not reduced, and a production method. That is, an oven controlled crystal oscillator in which pre-tinning solders are formed around openings on a front surface and a rear surface of a substrate in which of a through hole for passing a metal lead therethrough is formed; and in a state where a metal lead including a solder layer (a pre-tinning solder) formed on its surface is inserted into the through hole of the substrate, the metal lead extending from the openings is soldered to the openings on the front surface and the rear surface of the substrate, so as to form a main solder, and a production method of the oven controlled crystal oscillator are provided.
