A lighting device includes a light source component, a circuit board component, and a case component. The circuit board component is configured to supply power to the light source component. The case component houses the circuit board component in an interior of the case component. The circuit board component includes first and second circuit board components. The first circuit board component has a first mounting surface on which a first electronic part is mounted. The second circuit board component has a second mounting surface on which a second electronic part is mounted. The second mounting surface of the second circuit board component overlaps with the first mounting surface of the first circuit board component. |
