LIGHTING DEVICE

Provided is a lighting device capable of minimizing damage of a joint portion between an operation switch and a substrate or the substrate itself due to a force when the operation switch is operated and improving assemblability. The lighting device includes a housing installed in a vehicle, a substrate fixed to the housing, a cover member which is fixed to the housing and presses down the substrate, a light emitting element installed on the substrate, an operation switch which is installed on the substrate and switches the light emitting element on/off by being operated in directions of coming into contact with and moving away from the substrate, and a movement restricting portion which is formed in the housing, engages with a part of the operation switch and restricts movement of the operation switch toward the substrate side.
