An optical module and a manufacturing method thereof are provided which can 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 this case, the barrel and the lens holder are assembled with a brazing material inserted therebetween. The assembled barrel and lens holder are heated, and the brazing material is melted to thereby perform brazing. Lens glass is sandwiched between metal dies and a lens is press-molded using a pressing apparatus. In this case, positioning of press molding is performed using the barrel for which a small linear expansion coefficient is set as a reference.
