An opto-electric hybrid module is provided which has sufficient flexibility with its electric circuit properly covered with a film even if the film is formed by a photolithography process employing a photosensitive resin having a higher solvent content. In the opto-electric hybrid module, a linear light-path core (2) and an electric circuit including mounting pads (4a) and an electric circuit body (4) are provided on a surface of an under-cladding layer (1) of an optical waveguide (W). An optical element (5) is mounted with its electrodes (5a) in abutment against the mounting pads (4a). The electric circuit body (4) and a portion of the surface of the under-cladding layer (1) other than an electric circuit formation portion are covered with a stack (6) including a core material layer (2a) and an over-cladding material layer (3a). A surface portion (B) of the stack (6) present between the mounting pads (4a) and the electric circuit body (4) is located at a lower height position than a surface portion (A) of the stack (6) present on the electric circuit body (4). |
