Abstract
The present invention provides a polymer optical waveguide containing: a core; and a cladding having a refractive index lower than that of the core, provided around the core, in which the polymer optical waveguide has a core-coupling section where at least a part of the cladding is not present along a light propagation direction of the polymer optical waveguide and an application type removal film A provided so as to come into contact with the core of the core-coupling section.
