PROBLEM TO BE SOLVED: To provide a brazed flow channel plate capable of reducing a probability of plugging of a flow channel by a melted brazing filler metal in the brazed flow channel plate formed by using paired brazing sheets. SOLUTION: In this brazed flow channel plate constituted by adhering the brazing sheets respectively having a sheet core material composed of a metallic material and a brazing material attached to the front and back of the sheet core material as the pair of front and back, and forming a flow channel by a recessed portion formed on at least one of the adhesive opposed faces of the brazing sheets, a wedge-shaped space for allowing the brazing filler metal to enter therein by capillary phenomenon, is formed on the adhesive opposed faces of the pair of brazing sheets at least at one side in the extending direction of the flow channel.
