A method for producing a polymeric optical guide including steps of allowing the patterned surface of a patterned substrate (1) on which the pattern of grooves to become capillaries is provided to contact with a plane substrate (2), forming capillaries (1a through 1f) from the grooves, filling the capillaries with a monomer solution (6) which is the material for the core of the optical waveguide utilizing a capillary phenomenon, and polymerizing the monomer solution.
