PROBLEM TO BE SOLVED: To prevent a ground terminal from being covered with a sealant even when the sealant has been solidified after flowing into the central part side of a substrate from a mating part side of the substrate and a body.SOLUTION: An exposure device 100 comprises: a substrate 60 having light-emitting elements 62 mounted on the surface; a body 80 in which the substrate 60 and an optical element 70, which images light emitted from the light-emitting elements 62, are fixed so that the substrate 60 and the optical element 70 face each other; a sealant 90 for sealing a mating part 92 of the substrate 60 and the body 80 from a rear face side of the substrate 60; and a conductive component 64 which is mounted on a ground element 63 formed on the rear face of the substrate 60 and has a height H1 from the rear face, which is higher than the height of the end part of the central part side of the substrate 60 in the sealant 90. |
