A dartboard has a plurality of auto-returning target plates fitted in a grid frame which is enclosed in an outer ring, and has a grid fixed on a front end of the grid frame, a rear board mounted on rear ends of the grid frame and the outer ring, and an electric circuit board mounted on a rear end of the rear board. Each spring has a first end thereof positioned by a corresponding guide element, and a second end thereof extended through the corresponding hole of the rear board and lightly contacted with the electric circuit board. The auto-returning target plates are able to be depressed when darts are thrown and stick on the target plate and automatically returned to an original position by resilience of the springs.
