Abstract
To provide an optical fiber cable having a protective structure of an optical fiber connecting part that allows easy fabrication of a protective structure part having a decreased diameter without use of a metal rod and a heat-shrinkable tube, and a method for manufacturing the same. The problem is solved by an optical fiber cable () comprising a connecting part () of two optical fibers (A,B), each configured by an optical fiber core wire () and a coating material () coating the optical fiber core wire (), formed by peeling off the coating material () at tip end portions thereof, abutting tip ends of the optical fiber core wires () thus exposed against each other, and fusing and splicing the tip ends together, a resin cured product () provided to an outer periphery of the connecting part () to have an outer diameter that is the same or substantially the same as an outer diameter of a portion of the optical fiber provided with the coating material (), a metal pipe () provided to an outer periphery of the resin cured product () with an adhesive layer () interposed therebetween, and an outer sheath () composed of a resin tube or an extruded resin layer and covering an entire length including the metal pipe ().
