PROBLEM TO BE SOLVED: To provide a hot-melt sealer composition that has a high shear force and an excellent slip resistance combined, when it is hot (at a high temperature). SOLUTION: The hot-melt sealer composition contains 100 pts.mass of butyl rubber, 500-1,000 pts.mass of polyolefin A having a softening point of lower than 130°C, and 50-400 pts.mass of polyolefin B having a softening point of 130-150°C.
