A sealant capable of tightly sealing an electric device at a low temperature and a sealing method of using the sealant are provided. The sealant for molding and sealing a device comprises a copolyamide-series resin powder. The copolyamide-series resin may be a crystalline resin. The copolyamide-series resin may have a melting point or softening point of 75 to 160° C. The copolyamide-series resin may be a multiple copolymer, e.g., a binary or ternary copolymer. Further, the copolyamide-series resin may contain a unit derived from a long-chain component having a C8-16alkylene group (at least one component selected from the group consisting of a C9-17lactam and an aminoC9-17alkanecarboxylic acid).
