The invention provides an electrical connection box and a wire harness which appropriately ensure cooling performance. An electrical connection box (10) is provided with a heat-generating component (11) and a cooling unit (12) for cooling the heat-generating component (11), and the cooling unit (12) comprises: a recess (4) provided at a holding position of the heat-generating component (11) in a resin housing (3) that holds the heat-generating component (11); a seal (5) that is provided along the periphery of the recess (4), is compressed by contact with the heat-generating member (11), and closes the recess (4) together with the heat-generating member (11); and a heat-conducting member (6) which is housed in the recess (4) and in the interior surrounded by the seal (5), which solidifies and comes into contact with the heat-generating member (11) when the heat-generating member (11) does not generate heat, and which liquefies as the heat-generating member (11) generates heat.
本发明提供一种适当地确保冷却性能的电气连接箱以及线束。电气连接箱(10)具备发热部件(11)和对发热部件(11)进行冷却的冷却部(12),冷却部(12)包括:凹部(4),其在保持发热部件(11)的树脂框体(3)中设置于发热部件(11)的保持位置;密封件(5),其沿着凹部(4)的周缘设置,通过与发热部件(11)的接触而被压缩,与发热部件(11)一起封闭凹部(4);及导热部件(6),其容纳于凹部(4)和由密封件(5)包围的内部,在发热部件(11)不发热时固化而与发热部件(11)接触,且伴随着发热部件(11)的发热而液化。
