Abstract
To provide an optical module and a method for aligning the optical module with which alignment can be easily performed. An optical module includes first optical element sections and a second optical element section optically joined to the first optical element sections. Each first optical element section includes an optical conversion element, a ferrule having a distal end being in contact with and optically joined to the second optical element section, and a first optical system disposed in a position where the ferrule and the optical conversion element are optically adjusted. The second optical element section includes joining sections in contact with and joined to, in joining parts, the distal ends of the ferrules, a wavelength multiplexing optical element optically joined to the optical conversion elements, and second optical systems respectively disposed in positions where the wavelength multiplexing optical elements and the joining parts are optically adjusted.
