PROBLEM TO BE SOLVED: To provide a fin material with suppressing bondability reduction or rigidity reduction by suppressing sheet thickness reduction during binding heating and a brazing sheet using the same and a heat exchanger using the fin material and the brazing sheet.SOLUTION: There is provided a minimum alloy-made fin material consisting of an aluminum alloy containing Si: 1.50 to 5.00 mass% and the balance Al with inevitable impurities and having heating binding function as a single layer, all Si particle satisfying D≥L and L+D0.04 t satisfies 0≤ΣπD0.08 tW, where D is circle equivalent diameter of the Si particles, L is distance from a surface layer to a center of the Si particles, t is thickness of the fin material, W is length parallel to the surface layer on a cross section along a thickness direction of the fin material. There is provided an aluminum alloy-made brazing sheet using the same and a heat exchanger 10 using the fin material or the brazing sheet for a fin 12.SELECTED DRAWING: Figure 1
