PROBLEM TO BE SOLVED: To provide an optical fiber module which can suppress optical connection loss through easy optical axis alignment without using any expensive optical axis aligning member unlike before to eliminate optical axis deviation between optical fibers or an optical fiber and a light emission and reception unit when the both are optically connected to each other and further protect a connection end part at the tip of an optical fiber against damage due to contacting. SOLUTION: A taper ring (optical axis aligning member) 40 molded in a different single body while fitted in the inner circumference of a cylindrical optical fiber connection sleeve 30 is only set and this taper ring 40 can be replaced according to specifications. Taper beveled parts 20b having the same tilt angle with a taper hole 42 of the taper ring 40 are formed at tip circumferential edges of ferrules 20 and 21 fixed to end parts of optical fibers 10 and 11, so the taper beveled parts 20b are brought into slide contact with the taper hole 42 while guided and then the optical axes C<SB>1</SB>and C<SB>2</SB>of the optical fibers 10 can automatically be aligned with each other through the ferrule 20 to eliminate the optical axis deviation S, so that the ferrule 20 can automatically be positioned by being moved to a specified position in the taper ring 40.
