<p><P>PROBLEM TO BE SOLVED: To provide an optical waveguide and a molding die capable of suppressing generation of shrinks or bubbles without increasing optical loss and capable of making a bulged-out resin layer as thin as possible. <P>SOLUTION: This optical waveguide 1 includes: a clad substrate 2; a waveguide core 3 that has an incident side reflection area 30 in one end and an exiting side reflection area 31 in the other, is formed of a hardening resin on the lower face 2b of the clad substrate 2, that reflects an optical signal entering from the outside with the incident side reflection area 30 to propagate to the other, and that reflects the optical signal on the exiting side reflection areas 31A-31D to emit externally; and a flow passage resin part 4 that is connected to a non-propagating region noncontributing to the propagation of the optical signal of the waveguide core 3 and that functions as a flow passage during the unhardened time of the hardening resin of the waveguide core 3. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
