PROBLEM TO BE SOLVED: To provide an optical connection device which dispenses with alignment work of the optical axis of an optical fiber and the optical axis of a micro lens and therefore is manufactured with increased yield and productivity. SOLUTION: The optical connection device 21 optically connects the light propagating in the plurality of optical fibers 24 provided on a substrate 22 and a plurality of optical elements 28 arranged at a position separated from the surface of the substrate 22. So called a lens fiber in which the core end of the tapered end part 24d is formed into a convex curved face to be turned into a convex lens part 24c, is used as the optical fiber 24. A mirror 26 is formed as a part of the substrate at the distal end side of the optical fiber (lens fiber) 24. The optical element 28 is arranged at the focused position of the light passing through the convex lens part 24c at the distal end part of the optical fiber 24 and reflected on the mirror 26. The focused position onto the optical element 28 is determined only by the optical system on the side of the substrate 22, consequently the optical axis adjustment for connecting the optical fiber to the optical element is facilitated.
