上記目的を達成するために、本発明に係る金属端子は、底体、及び、当該底体の幅方向の両端からそれぞれ突出して形成され一部が相互に重なり合う一対の壁体によって箱状に形成され、内部の端子挿入空間部に前記幅方向と交差する軸方向に沿って相手端子を挿入可能である箱状部と、前記端子挿入空間部内に位置し前記箱状部に弾性変形可能に片持ち状に支持され前記相手端子との接点を形成するバネ接点部と、両面が粘着面をなすシート状に形成され、前記一対の壁体において相互に重なり合う部分に介在し当該重なり合う部分を相互に接着して当該一対の壁体の相対変位を規制する介在部材とを備えることを特徴とする。 In order to achieve the above object, the metal terminal according to the present invention is formed in a box shape by a bottom body and a pair of wall bodies that are formed so as to project from both ends in the width direction of the bottom body and partially overlap each other.

The metal terminal 1 is held, for example, in a connector C (see FIG. 5 or the like) described later. The metal terminal 1 of the present embodiment is a crimp terminal that is crimped to the terminal of the electric wire W, but is not limited to this.

ここで、図５、図６を参照して端子付き電線１００が適用されるワイヤハーネスＷＨ１について説明する。ワイヤハーネスＷＨ１は、例えば、車両に搭載される各装置間の接続のために、電源供給や信号通信に用いられる複数の電線Ｗを束にして集合部品（電線束）とし、コネクタＣ等で複数の電線Ｗを各装置に接続するようにしたものである。ワイヤハーネスＷＨ１は、少なくとも１つの端子付き電線１００と、端子付き電線１００を構成する電線Ｗに接続される接続相手電線ＷＡと、電線Ｗと接続相手電線ＷＡとが電気的に接続された分岐接続部ＪＴとを備える。ワイヤハーネスＷＨ１は、この他、さらに、コルゲートチューブ、グロメット等の外装部材、電気接続箱、固定具など種々の構成部品を含んで構成されてもよい。 Here, the wire harness WH1 to which the electric wire 100 with a terminal is applied will be described with reference to FIGS. 5 and 6. The wire harness WH1 is, for example, a bundle of a plurality of electric wires W used for power supply and signal communication to form a collective part (electric wire bundle) for connection between each device mounted on a vehicle, and a plurality of wire harnesses C and the like. The electric wire W is connected to each device. The wire harness WH1 is a branch connection in which at least one electric wire 100 with a terminal, a connection partner electric wire WA connected to the electric wire W constituting the electric wire 100 with a terminal, and the electric wire W and the connection partner electric wire WA are electrically connected. It is equipped with a part JT. In addition to this, the wire harness WH1 may be configured to include various components such as a corrugated tube, an exterior member such as a grommet, an electric connection box, and a fixture.

本実施形態のワイヤハーネスＷＨ１は、複数（ここでは、４つ）の端子付き電線１００を備える電線束であり、当該複数の端子付き電線１００の各電線Ｗが分岐接続部ＪＴで相互に接合されている。この分岐接続部ＪＴは、複数の電線Ｗのつなぎ部分（ジョイント部分）を構成するものであり、言い換えれば、複数の電線Ｗが分岐する分岐部分を構成するものであるということもできる。この場合、ワイヤハーネスＷＨ１は、各端子付き電線１００において、残りの他の端子付き電線１００の電線Ｗが接続相手電線ＷＡに相当することとなる。言い換えれば、各端子付き電線１００は、電線Ｗと接続相手電線ＷＡとが接続される分岐接続部ＪＴを備えているということもできる。 The wire harness WH1 of the present embodiment is an electric wire bundle including a plurality of (here, four) electric wires with terminals 100, and each electric wire W of the plurality of electric wires with terminals 100 is joined to each other by a branch connection portion JT. ing. This branch connection portion JT constitutes a connecting portion (joint portion) of a plurality of electric wires W, in other words, it can be said that it constitutes a branch portion in which a plurality of electric wires W branch. In this case, in the wire harness WH1, in each terminal-attached electric wire 100, the electric wire W of the remaining other terminal-attached electric wires 100 corresponds to the connection partner electric wire WA. In other words, it can be said that the electric wire 100 with each terminal includes a branch connection portion JT to which the electric wire W and the connection partner electric wire WA are connected.

本実施形態の各電線Ｗは、両端部において、導体部Ｗ１が絶縁被覆部Ｗ２から露出している。そして、各電線Ｗは、一方の端部に金属端子１が設けられ、当該金属端子１がそれぞれコネクタＣのハウジングに保持される一方、他方の端部同士が分岐接続部ＪＴで相互に接合されている。 In each electric wire W of the present embodiment, the conductor portion W1 is exposed from the insulating coating portion W2 at both ends. Each electric wire W is provided with a metal terminal 1 at one end, and the metal terminal 1 is held in the housing of the connector C, while the other ends are joined to each other by a branch connection portion JT. ing.

本実施形態の分岐接続部ＪＴは、電線Ｗと接続相手電線ＷＡとが超音波接合された超音波接合部ＵＷ１を形成する。超音波接合部ＵＷ１は、各電線Ｗにおいて、絶縁被覆部Ｗ２から露出した導体部Ｗ１同士を超音波接合した部分である。超音波接合部ＵＷ１は、各導体部Ｗ１の当該接合部分が絶縁性を有する保護部材ＪＴＨによって覆われ、保護されている。 The branch connection portion JT of the present embodiment forms an ultrasonic bonding portion UW1 in which an electric wire W and a connection partner electric wire WA are ultrasonically bonded. The ultrasonically bonded portion UW1 is a portion of each electric wire W in which conductor portions W1 exposed from the insulating coating portion W2 are ultrasonically bonded to each other. The ultrasonic bonding portion UW1 is protected by covering the bonding portion of each conductor portion W1 with an insulating protective member JTH.

ここで、超音波接合とは、図７に例示するように、超音波接合機の振動子を構成するホーンＭ１によって接続対象に対して超音波振動を印加し、当該印加された超音波振動を用いて行う金属間接合である。この場合、接続対象である複数の電線Ｗは、露出した各導体部（芯線）Ｗ１を重ねた状態で、受け治具を構成するアンビルＭ２と上記ホーンＭ１とによって当該各導体部（芯線）Ｗ１が挟持され、当該重なった導体部Ｗ１に対してホーンＭ１により超音波振動が加振される。この結果、複数の電線Ｗは、典型的には、重ねられた導体部Ｗ１の接合面が超音波振動によって互いに擦れ合うことで塑性変形により固相状態で接合され、超音波接合部ＵＷ１が形成される。 Here, ultrasonic bonding means, as illustrated in FIG. 7, ultrasonic vibration is applied to a connection target by a horn M1 constituting an oscillator of an ultrasonic bonding machine, and the applied ultrasonic vibration is applied. It is a metal-to-metal bonding performed by using. In this case, the plurality of electric wires W to be connected are connected to each of the exposed conductor portions (core wires) W1 by the anvil M2 constituting the receiving jig and the horn M1 in a state where the exposed conductor portions (core wires) W1 are overlapped. Is sandwiched, and ultrasonic vibration is applied to the overlapping conductor portions W1 by the horn M1. As a result, the plurality of electric wires W are typically bonded in a solid state by plastic deformation because the bonding surfaces of the stacked conductor portions W1 rub against each other by ultrasonic vibration, and an ultrasonic bonding portion UW1 is formed. To.

上記のように構成されるワイヤハーネスＷＨ１は、超音波接合部ＵＷ１の形成過程で導体部Ｗ１に超音波振動が加振された際、当該振動が端子付き電線１００の電線Ｗを伝播し金属端子１に印加される。本実施形態の端子付き電線１００は、このような構造にあって、上記のように振動が加わる金属端子１に対して後述する介在部材４０を設けることで、適正な導通性能の確保を図ったものである。以下、再び、図１、図２を参照して金属端子１の各構成について詳細に説明する。 In the wire harness WH1 configured as described above, when ultrasonic vibration is applied to the conductor portion W1 in the process of forming the ultrasonic bonding portion UW1, the vibration propagates through the electric wire W of the electric wire 100 with a terminal and is a metal terminal.

介在部材４０は、例えば、図３に示すように、電線接続部１０、箱状部２０、バネ接点部３０等の各部に対応した形状に打ち抜かれ、キャリアＣＲに連結された展開状態の一枚の板金に対して貼付される。介在部材４０は、箱状部２０が折り曲げ成形される前に、当該箱状部２０において、天面部２３ｂの対向面２３ｂａに相当する部分に貼付される。また、介在部材４０は、箱状部２０において、天面部２２ｂの対向面２２ｂａに相当する部分に貼付されてもよい。そして、介在部材４０は、図４に示すように、電線接続部１０、箱状部２０、バネ接点部３０等の各部と共に折り曲げ成形され、金属端子１の各部が立体的に一体で形成された状態で、壁体２２の対向面２２ｂａと壁体２３の対向面２３ｂａとの間に介在した状態となる。 As shown in FIG. 3, the intervening member 40 is punched into a shape corresponding to each portion such as the electric wire connecting portion 10, the box-shaped portion 20, and the spring contact portion 30, and is connected to the carrier CR in a deployed state. It is affixed to the sheet metal of. The intervening member 40 is attached to a portion of the box-shaped portion 20 corresponding to the facing surface 23ba of the top surface portion 23b before the box-shaped portion 20 is bent and molded. Further, the intervening member 40 may be attached to a portion of the box-shaped portion 20 corresponding to the facing surface 22ba of the top surface portion 22b. Then, as shown in FIG. 4, the intervening member 40 is bent and molded together with each part such as the electric wire connecting part 10, the box-shaped part 20, the spring contact part 30, etc., and each part of the metal terminal 1 is formed three-dimensionally integrally. In this state, it is in a state of being interposed between the facing surface 22ba of the wall body 22 and the facing surface 23ba of the wall body 23.

以上で説明した端子付き電線１００、金属端子１は、電線接続部１０に連結された箱状部２０の端子挿入空間部２４に相手端子Ｔが挿入される。そして、金属端子１は、当該端子挿入空間部２４内に支持されたバネ接点部３０によって当該相手端子Ｔとの間に接点が形成される。このような構成において、金属端子１は、箱状部２０を構成する底体２１、及び、一対の壁体２２、２３のうち、一対の壁体２２、２３において相互に重なり合う部分に介在部材４０が介在する。この介在部材４０は、両面が粘着面をなすシート状に形成され、一対の壁体２２、２３において重なり合う重複部２５を相互に接着して当該一対の壁体２２、２３の相対変位を規制する。この構成により、金属端子１は、介在部材４０によって一対の壁体２２、２３の相対変位を規制することで箱状部２０自体や当該箱状部２０に弾性変形可能に支持されたバネ接点部３０の変形を抑制することができる。この結果、端子付き電線１００、金属端子１は、適正な導通性能を確保することができる。 In the electric wire 100 with terminals and the metal terminal 1 described above, the mating terminal T is inserted into the terminal insertion space 24 of the box-shaped portion 20 connected to the electric wire connecting portion 10. Then, the metal terminal 1 is formed into a contact with the mating terminal T by the spring contact portion 30 supported in the terminal insertion space portion 24. In such a configuration, the metal terminal 1 has an intervening member 40 in a portion of the bottom body 21 constituting the box-shaped portion 20 and the pair of wall bodies 22 and 23 that overlap each other in the pair of wall bodies 22 and 23. Intervenes. The intervening member 40 is formed in a sheet shape having adhesive surfaces on both sides, and the overlapping portions 25 of the pair of wall bodies 22 and 23 are bonded to each other to regulate the relative displacement of the pair of wall bodies 22 and 23. .. With this configuration, the metal terminal 1 is a spring contact portion that is elastically deformably supported by the box-shaped portion 20 itself or the box-shaped portion 20 by restricting the relative displacement of the pair of wall bodies 22 and 23 by the intervening member 40. The deformation of 30 can be suppressed. As a result, the electric wire 100 with terminals and the metal terminal 1 can ensure proper conduction performance.

例えば、金属端子１は、分岐接続部ＪＴを構成する超音波接合部ＵＷ１の形成過程で振動が電線Ｗを伝播し金属端子１に伝わっても箱状部２０自体や当該箱状部２０に弾性変形可能に支持されたバネ接点部３０が当該振動によって変形することを抑制することができ、振動に対する耐性を向上させることができる。これにより、金属端子１は、例えば、振動に伴う箱状部２０とバネ接点部３０との相対変位を抑制することができ、バネ接点部３０が過剰に弾性変形したり当該バネ接点部３０の基端部に大きな応力が作用したりすることを抑制することができる。したがって、金属端子１は、当該金属端子１に超音波振動が伝達されても、バネ接点部３０を介して相手端子Ｔとの間に接点を形成し導通接続することができる構成を適正に維持することができる。この結果、端子付き電線１００、ワイヤハーネスＷＨ１は、上記のように適正な導通性能を確保することができ、接続信頼性の低下を抑制することができる。 For example, the metal terminal 1 is elastic to the box-shaped portion 20 itself and the box-shaped portion 20 even if vibration propagates through the electric wire W and is transmitted to the metal terminal 1 in the process of forming the ultrasonic bonding portion UW1 constituting the branch connection portion JT. The deformably supported spring contact portion 30 can be suppressed from being deformed by the vibration, and the resistance to vibration can be improved. As a result, the metal terminal 1 can suppress the relative displacement between the box-shaped portion 20 and the spring contact portion 30 due to vibration, for example, and the spring contact portion 30 is excessively elastically deformed or the spring contact portion 30 is affected. It is possible to suppress the action of a large stress on the proximal end portion. Therefore, even if ultrasonic vibration is transmitted to the metal terminal 1, the metal terminal 1 properly maintains a configuration capable of forming a contact with the mating terminal T via the spring contact portion 30 and making a conductive connection. can do. As a result, the electric wire 100 with terminals and the wire harness WH1 can secure appropriate conduction performance as described above, and can suppress deterioration of connection reliability.

ここでは、以上で説明した端子付き電線１００、金属端子１は、一対の壁体２２、２３において相互に重なり合う重複部２５に介在する介在部材４０が粘着ジェルシートによって構成される。粘着ジェルシートによって構成される介在部材４０は、柔軟性と弾力性を有する傾向にある。このため、この金属端子１は、当該金属端子１に振動が付加された場合には、上記のように一対の壁体２２、２３の相対変位を規制するだけでなく、介在部材４０によって一対の壁体２２、２３の間で振動を吸収することもできる。この結果、端子付き電線１００、金属端子１は、箱状部２０やバネ接点部３０の振動自体を抑制することができるので、より適正な導通性能を確保することができ、接続信頼性の低下をさらに抑制することができる。 Here, in the electric wire 100 with terminals and the metal terminal 1 described above, the intervening member 40 interposed in the overlapping portion 25 overlapping each other in the pair of wall bodies 22 and 23 is composed of an adhesive gel sheet. The intervening member 40 made of the adhesive gel sheet tends to have flexibility and elasticity. Therefore, when vibration is applied to the metal terminal 1, the metal terminal 1 not only regulates the relative displacement of the pair of wall bodies 22 and 23 as described above, but also has a pair of intervening members 40. Vibration can also be absorbed between the walls 22 and 23. As a result, the electric wire 100 with terminals and the metal terminal 1 can suppress the vibration itself of the box-shaped portion 20 and the spring contact portion 30, so that more appropriate conduction performance can be ensured and the connection reliability is lowered. Can be further suppressed.

また、以上で説明した端子付き電線１００、金属端子１は、介在部材４０が軸方向Ｘに沿って箱状部２０の全長に渡って延在するように設けられる。この構成により、端子付き電線１００、金属端子１は、軸方向Ｘ周り方向に捻じれるような変形も好適に抑制することができる。この結果、端子付き電線１００、金属端子１は、より適正な導通性能を確保することができる。 Further, the terminal-equipped electric wire 100 and the metal terminal 1 described above are provided so that the intervening member 40 extends along the axial direction X over the entire length of the box-shaped portion 20. With this configuration, the electric wire 100 with terminals and the metal terminal 1 can be suitably suppressed from being twisted in the axial direction X. As a result, the electric wire 100 with terminals and the metal terminal 1 can ensure more appropriate conduction performance.

なお、上述した本発明の実施形態に係る端子付き電線、及び、金属端子は、上述した実施形態に限定されず、特許請求の範囲に記載された範囲で種々の変更が可能である。 The electric wire with a terminal and the metal terminal according to the above-described embodiment of the present invention are not limited to the above-mentioned embodiment, and various changes can be made within the scope of the claims.

以上の説明では、端子付き電線１００の各電線Ｗは、一方の端部に金属端子１が設けられ、他方の端部同士が超音波接合部ＵＷ１で相互に接合されるものとして説明したがこれに限らない。例えば、各電線Ｗは、両端部にそれぞれ金属端子１が設けられていてもよい。そして、超音波接合部ＵＷ１は、各電線Ｗの中腹部分において、絶縁被覆部Ｗ２から露出した導体部Ｗ１を超音波接合した部分であってもよい。 In the above description, each electric wire W of the electric wire 100 with a terminal is described as having a metal terminal 1 provided at one end and the other ends being joined to each other by an ultrasonic bonding portion UW1. Not limited to. For example, each electric wire W may be provided with metal terminals 1 at both ends thereof. The ultrasonically bonded portion UW1 may be a portion where the conductor portion W1 exposed from the insulating coating portion W2 is ultrasonically bonded in the middle portion of each electric wire W.

以上の説明では、ワイヤハーネスＷＨ１は、各端子付き電線１００において、残りの他の端子付き電線１００の電線Ｗが接続相手電線ＷＡとなるものとして説明したがこれに限らない。ワイヤハーネスＷＨ１は、少なくとも１つの端子付き電線１００を備えた上で、当該端子付き電線１００に対する接続相手電線ＷＡは、端子付き電線１００の電線Ｗでなくてもよい。 In the above description, in the wire harness WH1, in each terminal-attached electric wire 100, the electric wire W of the remaining other terminal-attached electric wires 100 is assumed to be the connection partner electric wire WA, but the present invention is not limited to this. The wire harness WH1 is provided with at least one terminal-attached electric wire 100, and the connection partner electric wire WA to the terminal-attached electric wire 100 does not have to be the electric wire W of the terminal-attached electric wire 100.

以上の説明では、端子付き電線１００は、超音波接合部ＵＷ１を備え、超音波接合部ＵＷ１の形成過程で金属端子１に振動が加わる構造であるものとして説明したがこれに限らない。端子付き電線１００は、超音波接合部ＵＷ１を備えず、金属端子１に超音波振動等が伝達されないものであってもよい。同様に、端子付き電線１００は、分岐接続部ＪＴを備えるものとして説明したがこれに限らず分岐接続部ＪＴを備えない構成であってもよい。これらの場合であっても、端子付き電線１００、金属端子１は、適正な導通性能を確保することができる。 In the above description, the electric wire 100 with terminals is described as having a structure in which the ultrasonic bonding portion UW1 is provided and vibration is applied to the metal terminals 1 in the process of forming the ultrasonic bonding portion UW1, but the present invention is not limited to this. The electric wire 100 with a terminal may not be provided with an ultrasonic bonding portion UW1 and may not transmit ultrasonic vibration or the like to the metal terminal 1. Similarly, although the electric wire 100 with terminals has been described as having the branch connection portion JT, the present invention is not limited to this, and the electric wire 100 may be configured not to include the branch connection portion JT. Even in these cases, the electric wire 100 with terminals and the metal terminal 1 can ensure proper conduction performance.

以上の説明では、端子付き電線１００は、例えば、車両等に使用されるワイヤハーネスＷＨ１等に適用されるものとして説明したがこれに限らない。 In the above description, the electric wire 100 with terminals has been described as being applied to, for example, a wire harness WH1 or the like used in a vehicle or the like, but the present invention is not limited to this.

以上の説明では、電線接続部１０は、電線Ｗに加締められて圧着される電線圧着部を構成するものとして説明したがこれに限らず、圧着以外の形式、例えば、溶着、締結等の形式で電線Ｗに対して電気的に接続されるものであってもよい。 In the above description, the electric wire connecting portion 10 has been described as constituting an electric wire crimping portion that is crimped and crimped to the electric wire W, but the present invention is not limited to this, and a form other than crimping, for example, a form such as welding or fastening. It may be electrically connected to the electric wire W.

例えば、図８に例示する変形例に係るワイヤハーネスＷＨ２は、端子付き電線２００を備え、当該端子付き電線２００は、金属端子２０１を備える。そして、ワイヤハーネスＷＨ２、端子付き電線２００、金属端子２０１は、電線接続部１０にかえて電線接続部２１０を備える点で上述したワイヤハーネスＷＨ１、端子付き電線１００、金属端子１と異なる。ワイヤハーネスＷＨ２、端子付き電線２００、金属端子２０１のその他の構成は、上述のワイヤハーネスＷＨ１、端子付き電線１００、金属端子１と略同様の構成である。 For example, the wire harness WH2 according to the modification illustrated in FIG. 8 includes an electric wire 200 with a terminal, and the electric wire 200 with a terminal includes a metal terminal 201. The wire harness WH2, the electric wire 200 with a terminal, and the metal terminal 201 are different from the above-mentioned wire harness WH1, the electric wire 100 with a terminal, and the metal terminal 1 in that the electric wire connecting portion 210 is provided instead of the electric wire connecting portion 10. Other configurations of the wire harness WH2, the electric wire 200 with terminals, and the metal terminal 201 are substantially the same as those of the wire harness WH1, the electric wire 100 with terminals, and the metal terminal 1 described above.

本変形例の電線接続部２１０は、板厚方向が高さ方向Ｚに沿う略矩形板状に形成される。ここでは、箱状部２０の底体２１（図１等参照）は、当該板状に形成された電線接続部２１０に連結される。そして、電線接続部２１０は、絶縁被覆部Ｗ２から露出した電線Ｗの導体部Ｗ１と超音波接合されることで超音波接合部ＵＷ２を形成する。つまり、この端子付き電線２００は、金属端子２０１自身にも超音波接合部ＵＷ２を備えている。ここでの超音波接合部ＵＷ２は、端子付き電線２００において、金属端子２０１の電線接続部２１０と電線Ｗの導体部Ｗ１とを超音波接合した部分である。 The electric wire connecting portion 210 of this modification is formed in a substantially rectangular plate shape in which the plate thickness direction is along the height direction Z. Here, the bottom body 21 of the box-shaped portion 20 (see FIG. 1 and the like) is connected to the electric wire connecting portion 210 formed in the plate shape. Then, the electric wire connecting portion 210 is ultrasonically bonded to the conductor portion W1 of the electric wire W exposed from the insulating coating portion W2 to form the ultrasonic bonding portion UW2. That is, the electric wire 200 with a terminal also includes an ultrasonic bonding portion UW2 on the metal terminal 201 itself. The ultrasonically bonded portion UW2 here is a portion of an electric wire 200 with a terminal in which the electric wire connecting portion 210 of the metal terminal 201 and the conductor portion W1 of the electric wire W are ultrasonically bonded.

端子付き電線２００は、図７の例と同様に、電線接続部２１０と導体部Ｗ１とを重ねた状態で、アンビルＭ２とホーンＭ１とによって電線接続部２１０と導体部Ｗ１とが挟持され、当該重なった部分に対してホーンＭ１により超音波振動が加振される。この結果、端子付き電線２００は、典型的には、重ねられた電線接続部２１０と導体部Ｗ１との接合面が超音波振動によって互いに擦れ合うことで塑性変形により固相状態で接合され、超音波接合部ＵＷ２が形成される。これにより、端子付き電線２００は、電線接続部２１０に電線Ｗを導通接続することができる。 In the electric wire 200 with terminals, the electric wire connecting portion 210 and the conductor portion W1 are sandwiched by the anvil M2 and the horn M1 in a state where the electric wire connecting portion 210 and the conductor portion W1 are overlapped with each other as in the example of FIG. Ultrasonic vibration is applied to the overlapped portion by the horn M1. As a result, the electric wire 200 with a terminal is typically bonded in a solid phase state by plastic deformation by rubbing the joint surface between the overlapped electric wire connection portion 210 and the conductor portion W1 against each other by ultrasonic vibration. The joint UW2 is formed. As a result, the electric wire 200 with a terminal can electrically connect the electric wire W to the electric wire connecting portion 210.

上記のように構成される端子付き電線２００、金属端子２０１は、金属端子２０１自身に超音波接合部ＵＷ２が形成されるような場合であっても、上記と同様に、箱状部２０に介在部材４０が設けられていることで適正な導通性能を確保することができる。 The electric wire 200 with a terminal and the metal terminal 201 configured as described above are interposed in the box-shaped portion 20 in the same manner as described above even when the ultrasonic bonding portion UW2 is formed on the metal terminal 201 itself. Proper conduction performance can be ensured by providing the member 40.

以上の説明では、介在部材４０は、粘着ジェルシートであるものとして説明したがこれに限らず、両面が粘着面をなす粘着シートであればよい。 In the above description, the intervening member 40 has been described as being an adhesive gel sheet, but the present invention is not limited to this, and any adhesive sheet having adhesive surfaces on both sides may be used.

本実施形態に係る端子付き電線、及び、金属端子は、以上で説明した実施形態、変形例の構成要素を適宜組み合わせることで構成してもよい。 The electric wire with a terminal and the metal terminal according to the present embodiment may be configured by appropriately combining the components of the embodiments and modifications described above.
