Abstract
An optical module and a manufacturing method improve positioning accuracy between parts. A barrel and a lens holder are prepared, the lens holder is fitted into a cylindrical portion from a collar portion side of the barrel, and the barrel and the lens holder are assembled. In one case, the barrel and the lens holder are assembled with a brazing material. The assembled barrel and lens holder are heated, and the brazing material is melted to braze the barrel and the lens holder. Lens glass is sandwiched between metal dies and a lens is press-molded using a pressing apparatus. In one case, positioning of press molding uses the barrel which has a small linear expansion coefficient.
