ABSTRACT:
An optical coupling element disposed between an optical fiber and an optical element that face each other and optically coupling these two facing components includes a substantially cylindrical optical coupling portion whose opposite end surfaces respectively face the optical fiber and the optical element; and a projection projecting radially from a periphery of the optical coupling portion and being located closer towards one of the opposite end surfaces with respect to a center position therebetween. A diameter of the optical coupling portion at a position corresponding to a first end surface of the projection is substantially equal to a diameter of the optical coupling portion at a position corresponding to a second end surface of the projection. The periphery of the optical coupling portion includes periphery surfaces tapered from the positions corresponding to the first and second end surfaces of the projection respectively towards the opposite end surfaces.
