PROBLEM TO BE SOLVED: To provide a waterproof seal material which can serve a prevention against leakage of water by only applying the material to site to be required, by preparing the material through mixing a hydrogenation diene polymer with an inorganic filler in an organic solvent. SOLUTION: A waterproof seal material is obtained by mixing a hydrogenation diene polymer of 100 pts.wt. with an inorganic filler of 1-50 pts.wt. in 100-500 pts.wt. of an organic solvent selected from toluene, cyclohexane and THF. The hydrogenation diene polymeris preferably hydrogenation rubber of a random diene compolymer of at least one of conjugated diene and a vinyl aromatic compound. The ocnjugated diene is not particularly limited, but is particlulary preferably 1,3-butane and isoprene. For example, a butadiene-styrene copolymer, an isoprene-styrene copolymer and the like is preferable. A double bond in a conjugate d diene chain of the hydrogenation diene polymer is preferable at least 80% of hydrogenation. The inorganic filler is preferably a layered silicate and anhydrous silica.
