PURPOSE:To array optical transmitters with extremely high precision and to obtain high resolution by foring nearly sectorial grooves in the nonparallel surface of a wedgelike plate type body, arranging the optical transmitters in those grooves, and stacking plate type bodies so that nonlinear surfaces face each other. CONSTITUTION:The optical transmitters 2 are arranged in individual grooves 15 of an upper reference plate 12 with the grooves 15 up. Then, a spacer 14 is arranged thereupon, and pins 26 are inserted into pin holes 23 and 21 to specify the relative positions of the upper reference plate 12 and spacer 14 at right angles to the pins 26. Then, those upper reference plate 12 and spacer 14 are fixed temporarily at projection parts 17 with an adhesive. Then, the optical transmitters 25 are arranged in the individual grooves 16 of a lower reference plate 13. Then, the upper reference plate 12, optical transmitters 24, and spacer 14 are inverted as shown in a figure, and the pins 26 are inserted into pin holes 22 to specify the relative positions of the upper reference plate 12, spacer 14, and lower reference plate 13 at right angles to the pins 26. Then, the upper reference plate 12, spacer 14, and lower reference plate 13 are fixed temporarily at the projection parts 17 with an adhesive.
