Abstract: Disclosed is a battery socket comprising an anode plate which is formed with a conductive plate, an insulator mounted between the anode plate and a cathode plate to prevent a short between the pole plates, which has a groove allowing a positive pole of the battery to pass through, and a cathode plate which is formed with a conductive plate and has a groove allowing the protruding portion (positive pole) to pass through and of which one side is contacted with the insulator and the other side is contacted with a flat portion (negative pole) of the battery. The cathode plate has a projecting plate for allowing easy contact with the flat portion (negative pole) of the battery. The anode plate has elastic members or a curve for relaxing the pressure when inserting the positive pole of the battery.
