A plurality of wavelength selective filters 71 to 74 with different selective wavelengths are disposed on a substrate 50, so that reflected light reflected by a filter is sequentially made incident, and fiber collimators 101 to 106 combined of an optical fiber terminal with a coreless fiber attached to its tip end and a lens are disposed on an optical path of incident light made incident to a filter on the uppermost stream side, on an optical path of transmitted light transmitted through each filter, and on an optical path of reflected light by a filter on the lowermost stream side. Each fiber collimator is alternately disposed on one side and the other side of one substrate, and positioned so as to be placed in V-grooves 61 to 66 formed on the same plane on the substrate. All of the V-grooves are formed on the same plane, and at least one set of the fiber collimators having a relation of facing to each other through the filter on one side and the other side is disposed on the same axial line.
