Abstract: An optical module includes a wiring board having a first electrode, an optical waveguide provided on the wiring board, an optical element having a second electrode and provided on the optical waveguide, a conductive bonding material bonding the first and second electrodes, and a fixing member that fixes the optical element to the optical waveguide. The optical waveguide includes a core layer, a first cladding layer provided on a first side of the core layer, a second cladding layer provided on a second side of the core layer opposite to the first side, and an optical path conversion mirror provided on the core layer or the second cladding layer. The optical element is optically coupled to one end of the core layer via the optical path conversion mirror, and a softening point of the fixing member is higher than a melting point of the conductive bonding material.
