Abstract
To suppress misalignment when a light-emitting element is mounted on a substrate. On the substrate of a light-emitting device, a through hole is formed passing through so as to notch the side surface of the substrate, and a side surface electrode is formed on the side surface of the through hole. The pattern of a front surface electrode has a first region, a second region being connected to the first region, and a third region being connected to the first region and the second region. The shape of the first region is a rectangle coinciding with the electrode of the light-emitting element, and the longitudinal direction of the rectangle is aligned with the longitudinal direction of the substrate. The second region is formed in a lid shape so as to cover the top of the through hole. The shape of the second region is a trapezoid.
