PROBLEM TO BE SOLVED: To provide a curable polyisobutylene composition which excels in heat resistance, weatherability, quick curability, and adhesion to inorganic and organic materials and can improve low moisture permeability and resistance to staining and a sealing medium. SOLUTION: The curable polyisobutylene composition comprises (A) a reactive polyisobutylene oligomer, (B) an adhesion imparting agent, (C) a filler, and (D) a curing catalyst and is used in various adhesives, sealing media and the like. By the chemical structure containing the polyisobutylene oligomer, the heat resistance, weatherability, quick curability, and adhesion to inorganic and organic materials are excellent, and furthermore the low moisture permeability and resistance to staining can be improved.
