To provide a crimp terminal, etc., capable of obtaining both excellent electrical connection and water blocking to achieve excellent close contact, even when a flat wire of a stator and the crimp terminal are dissimilar metals.SOLUTION: A crimp terminal comprises: a connector part 120 electrically connected with an external terminal; and a cylindrical crimp part 140 integrally provided through the connector part and a transition part 130 and crimped with a lead wire (flat wire) having an approximately rectangular cross section. The crimp terminal is integrally formed of, for example, copper or copper alloy and is attached to the lead wire having an aluminum or aluminium alloy conductor; A conductor crimp part 143 includes a protrusion 143a projected at an inside of the cylindrical crimped part 140 and electrically connected with the conductor of the lead wire 102; and a coated crimp part 142 has a protrusion 142a projected at the inside of the cylindrical crimp part 140 and fitted into the coated part of the lead wire 102.SELECTED DRAWING: Figure 18 【課題】ステータの平角線と圧着端子とが異種金属である場合であっても、良好な電気的接続および止水性を両立して、優れた密着性を実現することができる圧着端子等を提供する。【解決手段】 圧着端子は、外部端子と電気的に接続されるコネクタ部１２０と、該コネクタ部とトランジション部１３０を介して一体的に設けられ、断面略矩形の導線（平角線）と圧着される筒状圧着部１４０とを備えている。圧着端子は、例えば、銅あるいは銅合金で一体形成され、アルミニウムあるいはアルミニウム合金製の導体を有する導線に取り付けられる。導体圧着部１４３は、筒状圧着部１４０の内側に突出し、且つ導線１０２の導体と電気的に接続される突起部１４３ａを有している。また、被覆圧着部１４２は、筒状圧着部１４０の内側に突出し、且つ導線１０２の被覆部に嵌入される突起部１４２ａを有する。【選択図】図１８
