Abstract
An optical waveguide structure containing a plurality of core portions for transmitting light (L), in which adjacent core portions are arranged with substantially parallel central axes, and the optical paths of the light (L) that is transmitted through the adjacent core portions are in opposite directions, wherein each core portion has a tapered section in which the area of the cross-section in a direction substantially perpendicular to the central axis decreases gradually in the direction of the optical path of the light (L). A highly reliable electronic device containing the optical waveguide structure is also provided.
