PROBLEM TO BE SOLVED: To provide a terminal block capable of securing seal performance even when it is exposed to the environment subjected to a heat cycle.SOLUTION: A terminal block 1 comprises a housing 2 including a resin molding part 20, a bus bar 3 integrally including an embedded part 30 embedded in the resin molding part 20 and a connection part 31 protruding outward from the resin molding part 20, and a seal part 4 for sealing a space 5 existing between the embedded part 30 and the resin molding part 20. The seal part 4 is composed of a crosslinked body of an adhesive composition including a homopolymer rubber of epichlorohydrin and a second rubber composed of a nitrile rubber and/or an acrylic rubber. The adhesive composition contains a second rubber in an amount of 1-10 pts.mass to 100 pts.mass of the homopolymer rubber.SELECTED DRAWING: Figure 3 |
