The present invention relates to a method for producing a polymeric optical waveguide, comprising: preparing a mold having, on a surface thereof, a branched concave portion for forming a core; bringing a clad substrate into close contact with the surface of the mold having the branched concave portion; filling the branched concave portion with a core-forming curable resin by supplying and sucking the core-forming curable resin from one end of the branched concave portion into the branched concave portion toward another end of the branched concave portion which is provided opposite the one end while the remaining ends of the branched concave portion are closed, by opening the closed ends, and by sucking the core-forming curable resin into portions communicating with the opened ends; and curing the core-forming curable resin; and a production device used for the above method.
