PROBLEM TO BE SOLVED: To provide a light-emitting device manufacturing method capable of easily manufacturing a light-emitting device for highly accurately condensing the light emitted by a light-emitting element.SOLUTION: In a manufacturing process of a light print head, after determining a mounting position based on a reference position determined from a mounting position image of including a rod lens array 45, a light-emitting element array tip 43 is mounted on a substrate 42 by using a die bonder. At this time, the mounting position is determined with an apex P1 of the rod lens array 45 as the reference position on a first tip and with a positioning mark M1 of a just before tip as the reference position on a tip on and after a second one. Thus, the light print head can be manufactured by extremely highly accurately determining a relative position between the rod lens array 45 and the light-emitting element array tip 43.SELECTED DRAWING: Figure 5 |
