PROBLEM TO BE SOLVED: To provide a wavelength multiplex optical communication demultiplexer in which an optical fiber, the demultiplexer and a photodetector are mutually connected in an optically and highly precise manner, the size is compact, the production is simple and the production cost is low, to provide a manufacturing method of the demultiplexer and to provide an electronic equipment. SOLUTION: The wavelength multiplex optical communication demultiplexer is provided with a block 11 on which a guide 13 that has a recessed shape and is used to insert an optical fiber is arranged, a demultiplexer 30 which is an optical waveguide provided inside the block 11, has one end face that is exposed to the bottom surface of the recessed shape guide 13 and has the other end face that is exposed to the surface of the block 11 and minute tile shaped elements 1a, 1b, 1c and 1d which are pasted on the block 11 so as to oppose the end face of the demultiplexer 30.
