The present invention relates to a water-cooling type condenser, and more specifically, to a water-cooling type condenser including a fixing plate for fixing a gas and liquid separator, wherein the fixing plate is formed to enable a refrigerant and cooling water to flow by means of coupling between first and second plate portions, and is integrally formed, by brazing, with remaining components (a plate, a first inlet pipe, a first outlet pipe, a second inlet pipe, and a second outlet pipe), so as to enhance assemblability and durability and enable size reduction.
