Disclosed is an optical power splitter that can minimize the chip size with its manufacturing cost. The optical power splitter has one input optical waveguide and N output optical waveguides and splits an optical signal incident from the input optical waveguide into N optical signals. The optical power splitter includes at least two optical splitters having a structure of a planar lightwave circuit element and arranged apart from one another at predetermined intervals in a single chip, and an alignment waveguide for aligning the input and output optical waveguides of the plurality of optical splitters.
