A light emitting device includes a substrate, a first light emitting element, a second light emitting element, a first conductive pattern, and a second conductive pattern. The first conductive pattern is provided on the substrate and includes a first element mounting portion and a first wire connecting portion. The second conductive pattern is provided on the substrate to form a first wiring gap between the first conductive pattern and the second conductive pattern. A first recess is provided between the first element mounting portion and the first wire connecting portion and is in communication with the first wiring gap. At least a part of an outer shape of the first element mounting portion is defined by the first wiring gap and the first recess on a third side of the first element mounting portion adjacent to the second conductive pattern.
