A lighting apparatus includes a main body that is elongated; a light emitter disposed on a top surface of the main body; and a light-transmissive cover that is elongated along a lengthwise direction of the main body and covers the light emitter from above. The lighting apparatus includes a substrate having a major surface; and a receiver that is disposed on the major surface and receives the radio waves. The substrate is disposed on a side of the main body in the lengthwise direction, in such an orientation that the major surface intersects the lengthwise direction.
