<p>External air is prevented from entering a package through gaps between guide holes and guide pins of a sealed fiber array. A lower substrate (19) in which V grooves (20) and guide grooves (21) are formed in the lengthwise direction, and an upper substrate (23) having the same dimensions as those of the lower substrate (19) in the lengthwise direction and in the direction perpendicular thereto and disposed over the lower substrate (19), are provided. Guide holes are defined by the V grooves of the lower substrate (19) and the upper substrate (23). External air is prevented from entering, from the side where the guide holes for the sealed fiber array are provided, the side opposite thereto.</p> |
