Abstract: A refrigerator includes a shelf holder having holes along a vertical direction on a wall of a food storage chamber, and a shelf assembly attachable to the shelf holder via at least one of the holes. The refrigerator also includes an electronic device provided on the shelf assembly; a holder terminal unit provided between the shelf holder and the wall and having a holder-side terminal facing at least one of the holes; and a shelf terminal unit provided at a side of the shelf assembly that is configured to attach to the shelf holder. The shelf terminal unit has a pin configured to be inserted into and electrically connect with the holder-side terminal in a state in which the shelf assembly is attached to the shelf holder. The pin is electrically connected to the electronic device of the shelf assembly, and is longitudinally movable relative to the shelf terminal unit.
