Abstract
A production method of an optical waveguide includes: preparing a laminated body that includes a first clad layer and at least a core layer laminated on the first clad layer; forming a light propagating optical waveguide core by cutting the core layer by use of a dicing saw from a side where the core layer is laminated while intruding an edge of a blade portion of the dicing saw into the first clad layer so as to partially cut the first clad layer; and embedding at least a cut portion of the laminated body with a second clad layer.
