PROBLEM TO BE SOLVED: To provide the method and device for optical component alignment which can speedily and accurately determine an alignment position even if optical components have variance in size, etc. SOLUTION: A 1st optical connector is arranged on the side of a 1st stage 5 and a 2nd optical connector 4 is arranged on the side of a 2nd stage 6 respectively. On the side of the 1st stage 5, a laser 8 which emits laser light having a laser belt surface on an X-Y plane from the X-direction and a laser receiving device 9 are provided, and the distance between the left end of the laser belt plane and the connection end surface 32a of the 1st optical connector 3 is set to 50μm. A stage moving mechanism 25 moves a 2nd stage 6 to put the 2nd optical connector 4 close to the 1st optical connector 3, the cutoff quantity of the laser light cut off by the connection end surface 32b of the 2nd optical connector 4 is detected to detect the connection end surface interval between the 1st and 2nd optical connectors 3 and 4, and the movement quantity of the 2nd stage 6 is adjusted according of the connection end interval to determine the alignment positions of the 1st and 2nd optical connectors 3 and 4.
