The lower side cladding layer(101) of an optical wave guide and a core layer(102) are mounted on a substrate(100). The core layer forms a wave guide pattern by using a photolithography and a dry-etching method. At this time, an optical leakage area(200) is formed in a part bending the core layer. The optical wave guide(20) of PLC is formed by depositing an upper side cladding layer(103) on an etched silica core layer(102). A trench is formed by using the photolithography and a dry-etching process in a PLC in which the optical wave guide is formed, and a terrace(104) in which an optical transmitter(30) is flip-chipped is formed. The optical transmitter is bonded in a flip chip bonding in the formed terrace. The monitoring photodiode is laminated on the upper cladding layer.
