Abstract: A terminal block electrically relays inside and outside of a partition wall sealing a liquid. The terminal block includes a housing disposed so as to penetrate the partition wall, a bus bar inserted into the housing, a seal member attached to the housing so as to seal a gap between the bus bar and the housing, and a holder assembled to the housing outside the partition wall with respect to the seal member so as to prevent the seal member from coming off. The bus bar extends across the inside and outside of the partition wall through a first through hole of the housing, a seal hole of the seal member, and a second through hole of the holder. Durability of a material constituting the housing to the liquid is better than durability of a material constituting the holder to the liquid.

Abstract: A connector includes an integrated housing integrated with a shield shell, an end portion of an electric wire, and a terminal fitting in a state where a tip portion of the terminal fitting is exposed to the outside of the integrated housing so as to integrally fix the shield shell, the end portion of the electric wire, and also the terminal fitting.
