A door switch 10 includes: a rod 22 which is arranged to be movable relative to a vehicle main body and is biased when one door 100a moves toward a full-closed position; a switch casing 30 which is arranged to be movable relative to the vehicle main body and the rod 22 and is biased when the other door 100b moves toward a full-closed position; a detection unit which outputs a detection signal when the rod 22 and the switch casing 30 take predetermined relative positions; and a spring 23 (biasing member) which biases the rod 22 and the switch casing 30 to prevent the rod 22 and the switch casing 30 from taking the predetermined relative positions.
