Abstract
To provide a manufacturing method capable of highly accurately fixing a substrate and a lens array to a housing without making a manufacturing device complicated.SOLUTION: An exposure head includes: a substrate; a plurality of LEDs provided on the substrate; a lens array condensing light emitted from the plurality of LEDs to a surface to be irradiated; and a housing holding the substrate and the lens array. A manufacturing method of the exposure head includes a first step of fixing the substrate to the housing, and a second step of fixing the lens array to the housing after the first step.SELECTED DRAWING: Figure 11
