The present invention relates to a condenser, and more particularly, to a condenser in which a configuration and an assembly are simplified by forming a condensation region in which plates are stacked and refrigerant is condensed and a super cooling region in which the refrigerant is supercooled, arranging a connection plate to which a gas-liquid separator is coupled between the condensation region and the super cooling region, and forming the refrigerant and cooling water to flow between the condensation region and the super cooling region, in a water cooling condenser.
