Abstract
An issue is directed to suppressing light interference occurring between a plurality of waveguides and providing waveguides at high densities. Means for solving the issue includes a plurality of cores () each configured to allow light to be transmitted therethrough, a clad () surrounding the plurality of cores () and smaller in refractive index for light than each of the cores (), and a transmission suppression member () located between mutually adjacent two cores out of the plurality of cores () and configured to suppress transmission of light leaking from each of the cores.
