Abstract
An optical connector for connecting optical fibers, comprises: a guide-groove substrate having grooves for positioning optical fibers and guide pins; an upper plate having groove portions each for covering the guide pins positioned in the guide grooves of the guide-groove substrate; elastic guide-pin pressing members each provided in the groove portions of the upper plate above portions where the guide pin grooves are in contact with the guide pins. In such a arrangement, it is preferable to form an oxide film on said V-grooves of the guide-groove substrate at least in the vicinity of contact points between the guide pins and the V-grooves. The optical connector further includes a resin molding portion for surrounding the substrate and the upper plate, the resin molding portion including a pair of opposite opened portions at a front and back surfaces thereof.
