Abstract
An adhesive sheet for binding basic materials including an adhesive material layer with binding layer laminated on both sides, with the binding layer having a thickness of 6 to 20% of the thickness of the adhesive material layer. The binding layer contains a mixture of 20 to 70 weight % of a binder and 30 to 80 weight % of a mixed powder, where the mixed powder includes 60 to 66 weight % of flux powder, 30 to 33 weight % of aluminum and silicon alloy powder, and 1 to 10 weight % of cesium powder or lithium powder. The adhesive material layer is a mixture of 86 to 94 weight % of aluminum and 6 to 14 weight % of silicon. A brazing method for binding basic materials composed of aluminum alloy containing 0.2.about.2.5% of magnesium in aluminum prepares an adhesive sheet as described, binds the adhesive sheet at a binding point between the basic materials, and brazes the basic material to which the adhesive sheet is bound.
