Abstract
According to the present invention, a photosensitive resin composition for an optical waveguide contains a resin component and a photopolymerization initiator. The resin component has an absorbance of less than 0.03 as measured at 2960 cm−1 by an attenuated total reflection measurement (ATR) method by means of a Fourier transform infrared spectrophotometer (FT-IR), and includes a polymerizable substituent-containing resin as a main component. Where the inventive optical waveguide photosensitive resin composition is used as a material for the optical waveguide, particularly as a core layer formation material for the optical waveguide, it is possible to reduce a loss, for example, by avoiding vibrational absorption occurring at an optical waveguide transmission light wavelength of 850 nm due to a resin skeleton.
