PROBLEM TO BE SOLVED: To develop a powder/liquid-type adhesive material for a dental treatment comprising a combination of an aryl borate salt and an acid as a radical polymerization initiator, where the aryl borate salt can be uniformly dissolved easily in resin paste comprising a mixture of (I) a liquid material and (II) a powder material, and the polymerization reaction smoothly proceeds even when the adhesive material is subjected to a brush-on adhesion method to achieve high adhesive force. SOLUTION: The adhesive material for a dental treatment applied for the brush-on adhesion method comprises a curable material for a dental treatment comprising the liquid material (I) and the powder material (II) preserved separately and mixed before use, where the liquid material (I) comprises (i) a non-acidic (meth)acrylate monomer and (ii) the aryl borate salt while the powder material (II) comprises (i) an acidic substance soluble in the liquid material such as a substance bearing a sulfonic group and (ii) a resin powder.
