Abstract
The object is to provide an optical module for optical transmission which has a double resin structure wherein a transparent resin and a fixing resin are combined, which is low in price, and is easily produced. A package with a inside-and-outside double structure comprising an inner container having barriers filled with a transparent resin and a hard outer container formed of a fixing resin. The inner container stores the highly fluid transparent resin and prevents it from flowing out. The outer container provides mechanical strength and airtightness.
