To provide a connector capable of suppressing excessive rise in operation temperature of a terminal while avoiding increase in size of the connector.SOLUTION: A connector 1 comprises: a terminal 10 to be connected with an electric wire 2; and a housing 20 for accommodating the terminal 10. The housing 20 has a structural material composed of a heat sink 50 that can absorb heat generated at the terminal 10 as a part of a skeleton component constituting the housing 20. The housing 20 further comprises an insulative heat transfer member 80 that transfers heat from the terminal 10 to the heat sink 50. The heat transfer member 80 is arranged so that a part 82 of the heat transfer member 80 is in contact with the terminal 10 and another part 83 of the heat transfer member 80 is in contact with the heat sink 50. The heat transfer member 80 has a sheet-like shape, and comprises a through-hole 81 into which the terminal 10 is inserted and a slit 84 connecting between the through-hole 81 and an outer peripheral part of the heat transfer member 80.SELECTED DRAWING: Figure 5 【課題】コネクタの大型化を避けながら端子の動作温度の過度な上昇を抑制可能なコネクタを提供すること。【解決手段】コネクタ１は、電線２に接続されることになる端子１０と、端子１０が格納されるハウジング２０と、を備える。ハウジング２０は、端子１０に生じる熱を吸熱可能なヒートシンク５０で構成された構造材をハウジング２０を構成する骨格部品の一部として有する。ハウジング２０は、端子１０からヒートシンク５０に熱を伝える絶縁性の伝熱部材８０を、更に備え、伝熱部材８０は、伝熱部材８０の一部８２が端子１０に接触し、且つ、伝熱部材８０の他の一部８３がヒートシンク５０に接触する、ように配置される。伝熱部材８０は、シート状の形状を有し、端子１０が挿通される貫通孔８１と、貫通孔８１と伝熱部材８０の外周部とを繋ぐスリット８４と、を有する。【選択図】図５
