1. method for manufacturing optical waveguide, it has:

  • formed covering on the base material is formed be cured with resin, thereby form the operation of wrap down;

    Folded sandwich layer forms and uses resin film on this time wrap upper strata, thereby forms the operation of sandwich layer;

    This sandwich layer is carried out exposure imaging, thereby form the operation of core pattern;

    And will be cured with resin with the formed covering formation of the form of imbedding this core pattern, thereby the operation of formation upper clad layer,It is characterized in that, the operation of described formation sandwich layer forms the operation of using resin film for using roll laminating machine heat pressure adhesive sandwich layer on following wrap, and the operation of described formation upper clad layer is carried out the operation of heat pressure adhesive for using plate laminating machine under the atmosphere that reduces pressure.
