摘要： An optical scanning device 10 includes a VCSEL 17 and an emission unit 18 mounted on the same substrate 15, and a bottom plate portion 13a arranged on the lower side of the substrate 15. A columnar protruding portion 37 has a tapered shape and is plastically deformable, and is fixed to the bottom plate portion 13a The columnar protruding portion 37 has a distal end side inserted into a through hole portion 16 of the substrate 15. At least one of an upper portion of the columnar protruding portion 37 and the through hole portion 16 is plastically deformed so that they are fitted to each other. A relative inclination angle between the substrate 15 and the bottom plate portion 13a is defined by a fitting angle between the through hole portion 16 and the columnar protruding portion 37.
