Abstract
An optical transmission module which can provide hermetic sealing with reliability, is low in cost and excellent in mass productivity and a method of producing such an optical transmission module is provided. A sealing material is affixed to a cover section in advance. The sealing material is in the form of a film formed by screen printing along the joining portion between a body section and the cover section and having a thickness matching the amount of gap between the body section and the cover section at the joining portion. A conversion device is received in a recess of the body section, and an optical fiber is inserted into the body section from outside along a stepped portion and connected to the conversion device. With the cover section placed on the body section, the two are heated. As the sealing material, soldering paste is used, for example.
