PROBLEM TO BE SOLVED: To provide a sealing filler of photocuring type, having characteristics suitable for sealing gaps between parts composed of resin molded products, metals, etc., i.e., excellent pressure resistance, heat resistance, heat shock resistance, oil resistance, impact resistance, etc., and further having a short curing time. SOLUTION: This sealing filler of photocuring type contains (A) a liquid acrylic elastomer containing carboxy groups and having a weight-average molecular weight of 1,000-100,000, (B) (meth)acrylic acid or its derivative, (C) an isocyanato group-containing unsaturated compound, (D) a polyfunctional crosslinking agent having two or more unsaturated groups in its molecule, and (E) a photopolymerization initiator.
