Abstract
An object of the present invention is to very accurately position and align a plurality of optical fibers in each groove of a substrate for an optical fiber array, without leading to inappropriate upsizing and complication of an apparatus and increase in cost. To achieve the object, an optical-fiber aligning part 3 of a substrate 1 is formed, in parallel, with a plurality of grooves 2 at least on the top thereof, the plurality of grooves retaining and aligning a plurality of optical fibers 5. A cross section perpendicular to a longitudinal direction of the grooves 2 is recessed at a center portion of the top in the widthwise direction, and depths A of the grooves 2 provided at the center portion are shallower than depths A of the grooves 2 provided at both ends in the widthwise direction.
