Abstract
There are provided an optical waveguide forming resin composition, an optical waveguide and a light transmission flexible printed board both produced by using the composition, and a production method for the optical waveguide, wherein the resin composition is superior in coatability, capable of omitting a solvent drying step in coating film formation, and suitable as a material for forming an optical waveguide which allows only a low waveguide loss and which has a higher Tg and higher flexibility. An optical waveguide forming resin composition comprises the following components (A) through (D), wherein the optical waveguide forming resin composition is free from a solid resin component and the viscosity thereof under a 25° C. environment is within the range of 10 to 20 mPa·s:
