Abstract
To provide to a resin composition for an optical packaging material having a coefficient of thermal expansion approximately same as that of quartz and Pyrex (registered trade name) and capable of providing an optical packaging material exhibiting excellent flame retardancy and an optical packaging component, and an optical module and its production method. A molded body, an optical packaging component and an optical module having a low coefficient of thermal expansion and excellent flame retardancy can be obtained using a resin composition for an optical packaging material comprising a resin and inorganic fine particles which are made of a hydrolyzed condensate compound of an alkoxide compound and/or a carboxylic acid salt compound and have an average radius of gyration of 50 nm or smaller.
