　［本開示の実施形態の説明］
　最初に本開示の実施態様を列記して説明する。
　本開示の配線部材は、次の通りである。
　（１）複数の線状伝送部材を備える配線部材であって、前記複数の線状伝送部材は、前記複数の線状伝送部材に関する所定条件に応じて、少なくとも、複数の第１線状伝送部材と、複数の第２線状伝送部材とにグループ分けされ、前記複数の第１線状伝送部材を含む第１偏平配線部材と、前記複数の第２線状伝送部材を含む第２偏平配線部材とを備え、前記第１偏平配線部材の少なくとも一部と、前記第２偏平配線部材の少なくとも一部とが積層されている、配線部材である。本開示によると、同じグループの複数の線状伝送部材が同じ偏平配線部材に含められることから、積層された第１及び第２偏平配線部材を備える配線部材の作製し易くなる。
　（２）前記複数の線状伝送部材は、前記複数の線状伝送部材の接続先に応じて、少なくとも、前記複数の第１線状伝送部材と、前記複数の第２線状伝送部材とにグループ分けされてもよい。この場合、積層された第１及び第２偏平配線部材を配策し易くなる。
　（３）前記複数の線状伝送部材は、前記複数の線状伝送部材の種類に応じて、少なくとも、前記複数の第１線状伝送部材と、前記複数の第２線状伝送部材とにグループ分けされてもよい。この場合、同じ種類の線状伝送部材を同じ偏平配線部材に含めることができるため、積層された第１及び第２偏平配線部材を備える配線部材の作製し易くなる。
　（４）前記複数の第１線状伝送部材は、電源線あるいはグランド線を含み、前記複数の第２線状伝送部材は、信号線を含んでもよい。この場合、信号線は、比較的電流が多く流れる電源線あるいはグランド線とは別の偏平配線部材に含まれるため、信号線が電源線あるいはグランド線からの影響を受け難い。その結果、信号線にノイズが発生し難い。
　（５）前記複数の第１線状伝送部材は、車両の少なくとも一つの標準搭載品に接続され、前記複数の第２線状伝送部材は、前記車両の少なくとも一つのオプション品に接続されてもよい。この場合、オプション品は、標準搭載部品とは別の偏平配線部材に含まれる線状伝送部材と接続されるため、配線部材を作製する場合に、オプション品の有無に簡単に対応することができる。よって、配線部材を作製し易くなる。
　（６）前記複数の第１線状伝送部材は、第１エリアに位置する少なくとも一つの第１接続対象部に接続され、前記複数の第２線状伝送部材は、前記第１エリアとは異なる第２エリアに位置する少なくとも一つの第２接続対象部に接続されてもよい。この場合、第１及び第２偏平配線部材の線状伝送部材は、互いに異なるエリアに位置する接続対象部に接続されるため、積層された第１及び第２偏平配線部材を配策し易くなる。
　（７）前記複数の第１線状伝送部材は、前記第１偏平配線部材と前記第２偏平配線部材とを区別可能な色を示す少なくとも一つの線状伝送部材を含んでもよい。この場合、第１偏平配線部材と第２偏平配線部材とを区別することが可能となるため、第１及び第２偏平配線部材の積層工程において正確な積み重ねがなされ得る。
　（８）前記複数の第１線状伝送部材は、前記複数の第２線状伝送部材の少なくとも一つと異なる色を示す少なくとも一つの線状伝送部材を含んでもよい。この場合、第１偏平配線部材と第２偏平配線部材とを区別し易くなることから、第１及び第２偏平配線部材の積層工程において正確な積み重ねがなされ得る。
　（９）前記複数の第１線状伝送部材は、前記複数の第２線状伝送部材のそれぞれと異なる色を示す少なくとも一つの線状伝送部材を含んでもよい。この場合、第１偏平配線部材と第２偏平配線部材とをさらに区別し易くなることから、第１及び第２偏平配線部材の積層工程において正確な積み重ねがなされ得る。
　（１０）前記第１偏平配線部材は、前記複数の第１線状伝送部材に含まれる複数の第３線状伝送部材が曲がる曲がり部を有し、前記曲がり部では、前記複数の第３線状伝送部材のうち最小径の第３線状伝送部材が最も内側に位置する。この場合、曲がり部では、最小径の第３線状伝送部材よりも外側の径が大きい第３線状伝送部材の曲げ半径を大きくすることができる。よって、径が大きい第３線状伝送部材が曲げ易くなる。
　（１１）前記曲がり部では、径が大きいほど外側に位置するように前記複数の第３線状伝送部材が配置されている。この場合、第３線状伝送部材の径が大きいほど、第３線状伝送部材の曲げ半径を大きくすることができる。よって、複数の第３線状伝送部材が曲げ易くなる。
　［本開示の実施形態の詳細］
　本開示の配線部材の具体例を、以下に図面を参照しつつ説明する。なお、本発明はこれらの例示に限定されるものではなく、請求の範囲によって示され、請求の範囲と均等の意味および範囲内におけるすべての変更が含まれることが意図される。
　以下、実施形態に係る配線部材について説明する。図１は、配線部材１を示す概略平面図である。配線部材１は、積層された複数の偏平配線部材１０を備える。複数の偏平配線部材１０は、例えば、自動車の車両に搭載される複数の部品をつなぐ部材である。本例では、配線部材１は、積層された３つの偏平配線部材１０Ａ，１０Ｂ，１０Ｃを備える。配線部材１が備える積層された複数の偏平配線部材１０の数は２つであってもよいし、４つ以上であってもよい。配線部材１が備える複数の偏平配線部材１０の少なくとも一つは、分岐したり、曲がったりしてもよい。図１の例では、偏平配線部材１０Ｂ及び１０Ｃのそれぞれが曲がっている。
　配線部材１は、偏平配線部材１０Ａ，１０Ｂ，１０Ｃが積層された積層部分２を備える。積層部分２では、偏平配線部材１０Ａの少なくとも一部と、偏平配線部材１０Ｂの少なくとも一部と、偏平配線部材１０Ｃの少なくとも一部とが積層されている。本例の積層部分２では、偏平配線部材１０Ａの一部と、偏平配線部材１０Ｂの一部と、偏平配線部材１０Ｃの一部とが積層されている。
　図２は積層部分２の概略断面図である。各偏平配線部材１０は、複数の線状伝送部材１１及びシート１２を備える。線状伝送部材１１は、電気または光等を伝送する線状の部材である。本例では、線状伝送部材１１は、芯線と、当該芯線を覆う絶縁被覆とを含む電線である。芯線は、金属等の導電部材によって形成された線状導体である。芯線は１本または複数本の素線で構成される。絶縁被覆は、芯線の周囲を覆う絶縁部分である。線状伝送部材１１は、電線以外に、裸導線、シールド線、ツイスト線、エナメル線、ニクロム線あるいは光ファイバ等であってもよい。図２の例では、複数の線状伝送部材１１の径は互いに同じである。
　シート１２は、複数の線状伝送部材１１を偏平な形態に保つシート状の部材である。シート１２は、樹脂等によって形成される。シート１２は、金属を含んでいてもよい。シート１２は、不織シートを含んでもよい。シート１２の一方主面に複数の線状伝送部材１１が並列状態で固定される。シート１２に対する線状伝送部材１１の固定は、溶着、接着あるいは粘着等によってなされる。溶着は、超音波溶着であってもよいし、加熱溶着であってもよい。複数の線状伝送部材１１がシート１２の一方主面に固定されることによって、複数の線状伝送部材１１が平たい状態に保たれる。
　偏平配線部材１０は、上記例に限られない。複数の線状伝送部材１１は、平たい枠部材等によって偏平状態に保たれていてもよい。複数の線状伝送部材１１が偏平な形態となるように並列された形態で直接接合されていてもよい。また、偏平配線部材１０は、ＦＣＣ（Flexible　Flat　Cable）及びＦＰＣ（Flexible printed circuit）等のように、複数の線状導体が絶縁部材によって相互に絶縁された状態で偏平状態に保たれたものであってもよい。すなわち、偏平配線部材１０は、複数の線状導体が、相互に絶縁された状態で偏平な形態に保持され、全体として幅よりも厚みが小さく形成された配線部材であってもよい。
　積層部分２では、図２に示されるように、偏平配線部材１０Ａ、１０Ｂ，１０Ｃがこの順で積層されている。そして、偏平配線部材１０Ａの複数の線状伝送部材１１と、偏平配線部材１０Ｂのシート１２とが重なっており、偏平配線部材１０Ｂの複数の線状伝送部材１１と偏平配線部材１０Ｃのシート１２とが重なっている。
　偏平配線部材１０には、互いに径が異なる複数の線状伝送部材１１が含まれてもよい。図３の例では、偏平配線部材１０Ａ及び１０Ｂのそれぞれは、比較的径の大きい線状伝送部材１１ａと、比較的径の小さい線状伝送部材１１ｂとを含む。偏平配線部材１０Ｃは、比較的径の大きい線状伝送部材１１ａを含まず、比較的径の小さい線状伝送部材１１ｂを含む。図３の例では、偏平配線部材１０に含まれる複数の線状伝送部材１１の径の種類は２種類であるが、３種類以上であってもよい。
　また、積層された２つの偏平配線部材１０において、一方の偏平配線部材１０の複数の線状伝送部材１１と、他方の偏平配線部材１０の複数の線状伝送部材１１とが重なってもよい。図３の例では、偏平配線部材１０Ａの複数の線状伝送部材１１と、偏平配線部材１０Ｂの複数の線状伝送部材１１とが重なっている。
　図２の例では、積層部分２の断面視において、積層された２つの偏平配線部材１０の境界線は直線となっているが、曲がっていてもよい。図３～５は、積層された２つの偏平配線部材１０の境界線が曲がっている場合の積層部分２の断面構造例を示す図である。
　図３の例では、偏平配線部材１０Ａに含まれる径が小さい線状伝送部材１１ｂによって偏平配線部材１０Ａに凹んだ空間が生じている。また、偏平配線部材１０Ｂに含まれる径が大きい線状伝送部材１１ａによって偏平配線部材１０Ｂに出っ張り部分が生じている。そして、偏平配線部材１０Ａの凹んだ空間内に、偏平配線部材１０Ｂの出っ張り部分が配置されている。これにより、積層された２つの偏平配線部材１０Ａ及びＢの境界線２０は直線ではなく曲がっている。
　図４の例では、シート１２が柔軟に変形可能となっており、偏平配線部材１０Ｂのシート１２が、偏平配線部材１０Ａに含まれる径の小さい線状伝送部材１１ｂによって生じる凹んだ空間に応じて変形している。これにより、積層された２つの偏平配線部材１０Ａ及びＢの境界線は直線ではなく曲がっている。
　図５の例では、偏平配線部材１０Ａの幅方向の両端部が同じ方向に折り曲げられることによって生じる凹んだ空間に、偏平配線部材１０Ｂに含まれる複数の線状伝送部材１１ｂが配置されることによって、境界線２０が曲がっている。
　なお、積層部分２には、偏平配線部材１０Ａのすべてが含まれてもよい。つまり、積層部分２では、偏平配線部材１０Ａのすべてと、偏平配線部材１０Ｂの少なくとも一部と、偏平配線部材１０Ｃの少なくとも一部とが積層されてもよい。また、積層部分２には、偏平配線部材１０Ｂのすべてが含まれてもよいし、偏平配線部材１０Ｃのすべてが含まれてもよい。また、積層部分２は曲がった部分を有してもよい。
　また、偏平配線部材１０は、それが備える複数の線状伝送部材１１の少なくとも一つの少なくとも一方端に接続されたコネクタを備えてもよい。また、配線部材１は積層コネクタを備えてもよい。この場合、積層コネクタには、偏平配線部材１０Ａの少なくとも一つの線状伝送部材１１が接続されたコネクタと、偏平配線部材１０Ｂの少なくとも一つの線状伝送部材１１が接続されたコネクタと、偏平配線部材１０Ｃの少なくとも一つの線状伝送部材１１が接続されたコネクタとが含まれてもよい。
　積層部分２において、複数の偏平配線部材１０を積層状態に保つ構造は特に限定されない。例えば、積層部分２の周囲に粘着テープ等の結束部材が巻き付けられる構成が採用されてもよい。また、複数の偏平配線部材１０がそれらの間に介在する接着剤あるいは両面テープ等によって接着されてもよい。また、複数の偏平配線部材１０の両側部のシート１２が溶着、粘着テープあるいは接着剤等によって接合されること、あるいはクランプ等によって重ね合わせ状態に保たれる構成が採用されてもよい。
　ここで、配線部材１が備える複数の線状伝送部材１１は、当該複数の線状伝送部材１１に関する所定条件に応じて複数のグループに分けられている。本例では、配線部材１が備える複数の線状伝送部材１１は、複数の線状伝送部材１１を含む第１グループと、複数の線状伝送部材１１を含む第２グループと、複数の線状伝送部材１１を含む第３グループとに分けられている。そして、偏平配線部材１０Ａは第１グループの複数の線状伝送部材１１を含み、偏平配線部材１０Ｂは第２グループの複数の線状伝送部材１１を含み、偏平配線部材１０Ｃは第３グループの複数の線状伝送部材１１を含む。なお、配線部材１が備える複数の線状伝送部材１１は、２つのグループに分けられてもよいし、４つ以上のグループに分けられてもよい。
　このように、本例では、積層された複数の偏平配線部材１０について、同じグループの複数の線状伝送部材１１が同じ偏平配線部材１０に含められる。これにより、積層された複数の偏平配線部材１０を備える配線部材１を作製し易くなる。
　配線部材１が備える複数の線状伝送部材１１は、例えば、当該複数の線状伝送部材１１の接続先に応じて、第１グループ、第２グループ及び第３グループに分けられる。以下に、配線部材１が備える複数の線状伝送部材１１が接続先に応じてグループ分けされる場合の各偏平配線部材１０の接続先の例について説明する。
　配線部材１は、例えば、車両内の複数の接続対象部に接続される。配線部材１が接続される複数の接続対象部は複数の接続対象グループ３０に分けられている。複数の接続対象グループ３０は、例えば、少なくとも一つの接続対象部を含む接続対象グループ３０Ａと、少なくとも一つの接続対象部を含む接続対象グループ３０Ｂと、少なくとも一つの接続対象部を含む接続対象グループ３０Ｃとを含む（図１参照）。
　配線部材１が備える複数の線状伝送部材１１は、接続対象グループ３０Ａの接続対象部に接続される複数の線状伝送部材１１を含む第１グループと、接続対象グループ３０Ｂの接続対象部に接続される複数の線状伝送部材１１を含む第２グループと、接続対象グループ３０Ｃの接続対象部に接続される複数の線状伝送部材１１を含む第３グループとに分けられている。したがって、偏平配線部材１０Ａは、接続対象グループ３０Ａの接続対象部に接続される複数の線状伝送部材１１を含み、偏平配線部材１０Ｂは、接続対象グループ３０Ｂの接続対象部に接続される複数の線状伝送部材１１を含み、偏平配線部材１０Ｃは、接続対象グループ３０Ｃの接続対象部に接続される複数の線状伝送部材１１を含む。
　偏平配線部材１０Ａに含まれる複数の線状伝送部材１１の一端は、接続対象グループ３０Ａに含まれる少なくとも一つの接続対象部に接続される。偏平配線部材１０Ｂに含まれる複数の線状伝送部材１１の一端は、接続対象グループ３０Ｂに含まれる少なくとも一つの接続対象部に接続される。偏平配線部材１０Ｃに含まれる複数の線状伝送部材１１の一端は、接続対象グループ３０Ｃに含まれる少なくとも一つの接続対象部に接続される。複数の接続対象グループ３０の数は２つであってもよいし、４つ以上であってもよい。
　このように、本例では、積層された複数の偏平配線部材１０が、互いに異なる複数の接続対象グループ３０にそれぞれ接続される。つまり、積層された複数の偏平配線部材１０のそれぞれについて、偏平配線部材１０に含まれる複数の線状伝送部材１１を、同じ接続対象グループ３０の接続対象部に接続することができる。これにより、積層された複数の偏平配線部材１０のそれぞれを配策し易くなる。以下に、複数の接続対象部のグループ分けの例について説明する。
　図６はグループ分けの一例を説明するための図である。図６の例では、接続対象グループ３０Ａには、車両に搭載された回路の電源を出力する接続対象部が含まれる。例えば、接続対象グループ３０Ａには、電源ボックス１３０Ａが含まれる。本例では、偏平配線部材１０Ａの各線状伝送部材１１は電源線となる。
　接続対象グループ３０Ｂには、偏平配線部材１０Ｂの各線状伝送部材１１を接地するための接続対象部が含まれる。例えば、接続対象グループ３０Ｂには、接地された金属ボディ１３０Ｂが含まれる。本例では、偏平配線部材１０Ａの各線状伝送部材１１はグランド線となる。
　接続対象グループ３０Ｃには、信号の出力及び信号の入力の少なくとも一方が行われる接続対象部が含まれる。例えば、接続対象グループ３０Ｃには、コントローラ１３０Ｃが含まれる。本例では、偏平配線部材１０Ｃの各線状伝送部材１１は信号線となる。コントローラ１３０Ｃには、例えばＥＣＵ（Electronic Control Unit）が含まれる。
　偏平配線部材１０Ａの複数の線状伝送部材１１の一端は、電源ボックス１３０Ａに接続される。本例では、偏平配線部材１０Ａの複数の線状伝送部材１１の一端にコネクタ１３Ａが接続されている。コネクタ１３Ａは、電源ボックス１３０Ａが有するコネクタ１３１Ａに接続される。これにより、電源ボックス１３０Ａが出力する電源が、偏平配線部材１０Ａの各線状伝送部材１１に与えられる。
　偏平配線部材１０Ｂの複数の線状伝送部材１１の一端は、金属ボディ１３０Ｂに接続される。本例では、偏平配線部材１０Ｂの複数の線状伝送部材１１の一端にはアース端子１３Ｂが接続されている。アース端子１３Ｂはネジ止め等で金属ボディ１３０Ｂに固定される。これにより、偏平配線部材１０Ｂの各線状伝送部材１１は接地される。
　偏平配線部材１０Ｃの複数の線状伝送部材１１の一端は、コントローラ１３０Ｃに接続される。本例では、偏平配線部材１０Ｃの複数の線状伝送部材１１の一端にコネクタ１３Ｃが接続されている。コネクタ１３Ｃは、コントローラ１３０Ｃが有するコネクタ１３１Ｃに接続される。コネクタ１３１Ｃに出力端子が含まれる場合には、コントローラ１３０Ｃが出力する信号（例えば、回路を制御するための制御信号）が偏平配線部材１０Ｃの線状伝送部材１１に与えられる。また、コネクタ１３１Ｃに入力端子が含まれる場合には、偏平配線部材１０Ｃの線状伝送部材１１が伝達する信号（例えば、センサの検出信号）がコントローラ１３０Ｃに入力される。
　なお、接続対象グループには、複数の接続対象部が含まれてもよい。この場合、互いに近い位置に存在する複数の接続対象部が接続対象グループに含まれてもよい。
　例えば、接続対象グループ３０Ａには、複数の電源ボックス１３０Ａが含まれてもよい。この場合、偏平配線部材１０Ａの複数の線状伝送部材１１が複数の枝部に分岐され、当該複数の枝部が複数の電源ボックス１３０Ａにそれぞれ接続されてもよい。また、接続対象グループ３０Ａに含まれる電源を出力する接続対象部は電源ボックス１３０Ａ以外であってもよい。
　接続対象グループ３０Ｂには、接地された複数の接続対象部が含まれてもよい。この場合、偏平配線部材１０Ｂの複数の線状伝送部材１１が複数の枝部に分岐され、当該複数の枝部が、接地された複数の接続対象部にそれぞれ接続されてもよい。
　接続対象グループ３０Ｃには、複数のコントローラが含まれてもよい。この場合、偏平配線部材１０Ｃの複数の線状伝送部材１１が複数の枝部に分岐され、当該複数の枝部が複数のコントローラにそれぞれ接続されてもよい。接続対象グループ３０Ｃには、コントローラ以外が含まれてもよい。例えば、接続対象グループ３０Ｃには、信号を出力する少なくとも一つのセンサが含まれてもよい。
　図６の例に係る配線部材１では、信号線が、比較的多くの電流が流れる電源線とは別の偏平配線部材１０に含まれている。これにより、信号線が電源線からの影響を受け難い。よって、信号線にノイズが発生し難い。
　また図６の例では、信号線が、比較的多くの電流が流れるグランド線とは別の偏平配線部材１０に含まれている。これにより、信号線がグランド線からの影響を受け難い。よって、信号線にノイズが発生し難い。
　図７はグループ分けの他の例を説明するための図である。図７の例では、接続対象グループ３０Ａには、車両の標準搭載品２３０Ａが含まれる。標準搭載品２３０Ａは、例えば、ルームランプ、ハザードランプ、速度等を示すデジタルメータ、エアコンディショナーあるいはエアバック機構等の機器である。
　接続対象グループ３０Ｂには、車両のオプション品２３０Ｂが含まれる。ここで、オプション品には、標準搭載品に追加して車両に搭載される機器だけではなく、標準搭載品に替えて搭載される機器も含まれる。オプション品はオプション機器とも呼ばれる。標準搭載品に追加して車両に搭載される機器としては、例えば、フォグランプ、ドライブレコーダ、ＥＴＣ（Electronic Toll Collection System）車載器あるいはバックモニターカメラが考えられる。標準搭載品に替えて搭載される機器としては、例えば、標準搭載されるカーナビゲーション機器よりも性能が良いカーナビゲーション機器、標準搭載されるオーディオ機器よりも性能が良いオーディオ機器、あるいは標準搭載されるハロゲンヘッドライトの替わりに搭載されるＬＥＤ（Light Emitting Diode）ヘッドライト等が考えられる。オプション品２３０Ｂは、標準搭載品に追加して車両に搭載される機器であってもよし、標準搭載品に替えて搭載される機器であってもよい。
　接続対象グループ３０Ｃには、オプション品２３０Ｂとは異なるオプション品２３０Ｃが含まれる。オプション品２３０Ｃは、標準搭載品に追加して車両に搭載される機器であってもよし、標準搭載品に替えて搭載される機器であってもよい。車両の標準搭載品及びオプション品の種類は、車種、グレード等によって変化する。
　偏平配線部材１０Ａの複数の線状伝送部材１１の一端は、標準搭載品２３０Ａに接続される。本例では、偏平配線部材１０Ａの複数の線状伝送部材１１の一端にコネクタ１３Ａが接続されている。コネクタ１３Ａは、標準搭載品２３０Ａが有するコネクタ２３１Ａに接続される。
　偏平配線部材１０Ｂの複数の線状伝送部材１１の一端は、オプション品２３０Ｂに接続される。本例では、偏平配線部材１０Ｂの複数の線状伝送部材１１の一端にコネクタ１３ＢＢが接続されている。コネクタ１３ＢＢは、オプション品２３０Ｂが有するコネクタ２３１Ｂに接続される。
　偏平配線部材１０Ｃの複数の線状伝送部材１１の一端は、オプション品２３０Ｃに接続される。本例では、偏平配線部材１０Ｃの複数の線状伝送部材１１の一端にコネクタ１３Ｃが接続されている。コネクタ１３Ｃは、オプション品２３０Ｃが有するコネクタ２３１Ｃに接続される。
　なお、接続対象グループ３０には、複数の標準搭載品が含まれてもよい。この場合、互いに近い位置に存在する複数の標準搭載品が接続対象グループ３０に含まれてもよい。また、接続対象グループ３０には、複数のオプション品が含まれてもよい。この場合、互いに近い位置に存在する複数のオプション品が接続対象グループ３０に含まれてもよい。
　例えば、接続対象グループ３０Ａには、複数の標準搭載品が含まれてもよい。この場合、偏平配線部材１０Ａの複数の線状伝送部材１１が複数の枝部に分岐され、当該複数の枝部が複数の標準搭載品にそれぞれ接続されてもよい。同様に、接続対象グループ３０Ｂには複数のオプション品が含まれてもよいし、接続対象グループ３０Ｃには複数のオプション品が含まれてもよい。
　図７の例に係る配線部材１では、オプション品が、標準搭載品とは別の偏平配線部材１０の線状伝送部材１１に接続される。これにより、配線部材１を作製する場合に、オプション品の有無に簡単に対応することができる。よって、配線部材１を容易に作製することができる。例えば、オプション品２３０Ｃが搭載されない場合には、偏平配線部材１０Ｃを配線部材１に搭載しないことによって、オプション品２３０Ｃの有無に簡単に対応することができる。
　図８はグループ分けの他の例を説明するための図である。図８には、配線部材１が車両のルーフ５００に配策される様子が示されている。図８の例では、接続対象部が位置するエリアに応じて、複数の接続対象部がグループ分けされている。
　接続対象グループ３０Ａに含まれる接続対象部は、ルーフ５００の前方エリア５１０に位置する。接続対象グループ３０Ａには、例えば、ルーフ５００の前方エリア５１０に位置するルームランプが含まれる。偏平配線部材１０Ａの複数の線状伝送部材１１の一端は、前方エリア５１０に位置するルームランプに接続される。偏平配線部材１０Ａの複数の線状伝送部材１１の一端は、前方エリア５１０に位置する複数の接続対象部に接続されてもよい。
　接続対象グループ３０Ｂに含まれる接続対象部は、ルーフ５００の中央エリア５２０に位置する。接続対象グループ３０Ｂには、例えば、ルーフ５００の中央エリア５２０に位置するルームランプが含まれる。偏平配線部材１０Ｂの複数の線状伝送部材１１の一端は、中央エリア５２０に位置するルームランプに接続される。偏平配線部材１０Ｂの複数の線状伝送部材１１の一端は、中央エリア５２０に位置する複数の接続対象部に接続されてもよい。
　接続対象グループ３０Ｃに含まれる接続対象部は、ルーフ５００の後方エリア５３０に位置する。接続対象グループ３０Ｃには、例えば、ルーフ５００の後方エリア５３０に位置するアンテナが含まれる。偏平配線部材１０Ｃの複数の線状伝送部材１１の一端は、後方エリア５３０に位置するアンテナに接続される。偏平配線部材１０Ｃの複数の線状伝送部材１１の一端は、後方エリア５３０に位置する複数の接続対象部に接続されてもよい。
　なお、接続対象グループ３０に含まれる接続対象部の位置は上記の例に限られない。例えば、接続対象グループ３０Ａに含まれる接続対象部は、車両の前方のインストルメントパネルに位置してもよい。また、接続対象グループ３０Ａに含まれる接続対象部は、車両の後方のパネルに位置してもよい。
　図８の例に係る配線部材１では、複数の偏平配線部材１０の線状伝送部材１１は、互いに異なるエリアに位置する接続対象部に接続されることから、積層された複数の偏平配線部材１０を配策し易くなる。
　上記の例では、配線部材１が備える複数の線状伝送部材１１は、接続先に応じて複数のグループに分けられているが、他の条件に応じて複数のグループに分けられてもよい。例えば、配線部材１が備える複数の線状伝送部材１１は、複数の線状伝送部材１１の種類に応じて複数のグループに分けられてもよい。これにより、同じ種類の複数の線状伝送部材１１を同じ偏平配線部材１０に含めることができる。よって、積層された複数の偏平配線部材１０を備える配線部材１を作製し易くなる。以下に、この場合の複数の例について説明する。
　配線部材１が備える複数の線状伝送部材１１は、例えば、線状伝送部材１１の径に応じて複数グループに分けられてもよい。例えば、配線部材１が備える複数の線状伝送部材１１は、径が大きい複数の線状伝送部材１１を含む第１グループと、径が中程度の複数の線状伝送部材１１を含む第２グループと、径が小さい複数の線状伝送部材１１を含む第３グループとに分けられてもよい。この場合、第１グループに含まれる径が大きい複数の線状伝送部材１１は偏平配線部材１０Ａに含められる。また、第２グループに含まれる径が中程度の複数の線状伝送部材１１は偏平配線部材１０Ｂに含められる。そして、第３グループに含まれる径が小さい複数の線状伝送部材１１は偏平配線部材１０Ｃに含められる。
　また、配線部材１が備える複数の線状伝送部材１１は、線状伝送部材１１の芯線の材料に応じて複数グループに分けられてもよい。この場合、複数のグループには、例えば、芯線がアルミニウムで構成された複数の線状伝送部材１１を含む第１グループと、芯線が銅で構成された複数の線状伝送部材１１を含む第２グループとが含まれてもよい。なお、第３グループには、例えば、芯線の径が同じ複数の線状伝送部材１１が含められてもよい。
　また、配線部材１が備える複数の線状伝送部材１１は、線状伝送部材１１の芯線の形状に応じて複数グループに分けられてもよい。この場合、複数のグループには、例えば、芯線が撚り線である複数の線状伝送部材１１を含む第１グループと、芯線が単線である複数の線状伝送部材１１を含む第２グループとが含められてもよい。なお、第３グループには、例えば、芯線の径が同じ複数の線状伝送部材１１が含められてもよい。
　また、配線部材１が備える複数の線状伝送部材１１は、線状伝送部材１１の芯線を構成する金属の圧縮率に応じて複数グループに分けられてもよい。例えば、配線部材１が備える複数の線状伝送部材１１は、芯線を構成する金属の圧縮率が高い複数の線状伝送部材１１を含む第１グループと、芯線を構成する金属の圧縮率が中程度の複数の線状伝送部材１１を含む第２グループと、芯線を構成する金属の圧縮率が低い複数の線状伝送部材１１を含む第３グループに分けられてもよい。
　なお、配線部材１が備える複数の線状伝送部材１１が、線状伝送部材１１の種類に応じて複数のグループに分けられる場合には、配線部材１が接続される複数の接続対象部は複数の接続対象グループ３０に分けられなくてもよい。
　＜線状伝送部材が示す色について＞
　次に、偏平配線部材１０が備える線状伝送部材１１が示す色、つまり線状伝送部材１１の外周面の色について説明する。本例では、線状伝送部材１１は、芯線と、当該芯線を覆う絶縁被覆とを含む電線であることから、線状伝送部材１１が示す色とは、芯線を覆う絶縁被覆の外周面の色であると言える。
　偏平配線部材１０に含まれる複数の線状伝送部材１１が示す色は同じであってもよい。この場合、複数の偏平配線部材１０の間で、線状伝送部材１１が示す色が同じであってもよいし、異なっていてもよい。前者の場合には、配線部材１が備えるすべての線状伝送部材１１が示す色が同じとなる。この場合、配線部材１が備える各線状伝送部材１１が示す色は、黒色であってもよいし、その他の色であってもよい。
　図９は線状伝送部材１１が示す色の一例を説明するための図である。図９及び後述の図１０では、説明の便宜上、偏平配線部材１０Ａ，１０Ｂ，１０Ｃが積層されずに離れて示されている。図９及び後述の図１０では、同じ色を示す複数の線状伝送部材１１には同じハッチングが示されており、異なる色を示す複数の線状伝送部材１１には異なるハッチングが示されている。
　図９の例では、偏平配線部材１０Ａの複数の線状伝送部材１１が示す色は同じとなっている。また、偏平配線部材１０Ｂの複数の線状伝送部材１１が示す色は同じとなっている。また、偏平配線部材１０Ｃの複数の線状伝送部材１１が示す色は同じとなっている。一方で、複数の偏平配線部材１０Ａ，１０Ｂ，１０Ｃの間では、線状伝送部材１１が示す色は異なっている。偏平配線部材１０Ａの各線状伝送部材１１が示す色は例えば黒色である。偏平配線部材１０Ｂの各線状伝送部材１１が示す色は例えば赤色である。偏平配線部材１０Ｃの各線状伝送部材１１が示す色は例えば青色である。
　ここで、偏平配線部材１０Ａに着目する。図９の例では、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ｂの複数の線状伝送部材１１のそれぞれと異なる色を示す線状伝送部材１１を含んでいる。これにより、偏平配線部材１０Ａは偏平配線部材１０Ｂと区別することが可能である。したがって、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ａと偏平配線部材１０Ｂとを区別可能な色を示す線状伝送部材１１を含んでいると言える。また、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ｃの複数の線状伝送部材１１のそれぞれと異なる色を示す線状伝送部材１１を含んでいる。これにより、偏平配線部材１０Ａは偏平配線部材１０Ｃと区別することが可能である。したがって、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ａと偏平配線部材１０Ｃとを区別可能な色を示す線状伝送部材１１を含んでいると言える。
　同様にして偏平配線部材１０Ｂに着目すると、偏平配線部材１０Ｂの複数の線状伝送部材１１は、偏平配線部材１０Ｂと偏平配線部材１０Ａとを区別可能な色を示す線状伝送部材１１を含んでいると言える。また、偏平配線部材１０Ｂの複数の線状伝送部材１１は、偏平配線部材１０Ｂと偏平配線部材１０Ｃとを区別可能な色を示す線状伝送部材１１を含んでいると言える。
　同様にして偏平配線部材１０Ｃに着目すると、偏平配線部材１０Ｃの複数の線状伝送部材１１は、偏平配線部材１０Ｃと偏平配線部材１０Ａとを区別可能な色を示す線状伝送部材１１を含んでいると言える。また、偏平配線部材１０Ｃの複数の線状伝送部材１１は、偏平配線部材１０Ｃと偏平配線部材１０Ｂとを区別可能な色を示す線状伝送部材１１を含んでいると言える。
　図１０は線状伝送部材１１が示す色の他の一例を説明するための図である。図１０の例では、複数の偏平配線部材１０Ａ，１０Ｂ，１０Ｃのそれぞれには、複数の偏平配線部材１０Ａ，１０Ｂ，１０Ｃの間で共通の色を示す線状伝送部材１１ｃが含まれている。線状伝送部材１１ｃが示す色は例えば黒色である。
　また、複数の偏平配線部材１０Ａ，１０Ｂ，１０Ｃのそれぞれには、他の偏平配線部材１０に含まれる各線状伝送部材１１と異なる色を示す線状伝送部材１１が含まれている。
　偏平配線部材１０Ａには、偏平配線部材１０Ｂに含まれる各線状伝送部材１１及び偏平配線部材１０Ｃに含まれる各線状伝送部材１１とは異なる色を示す１つの線状伝送部材１１ｄが含まれている。線状伝送部材１１ｄが示す色は例えば赤色である。偏平配線部材１０Ａには、２つ以上の線状伝送部材１１ｄが含まれてもよい。
　偏平配線部材１０Ｂには、偏平配線部材１０Ａに含まれる各線状伝送部材１１及び偏平配線部材１０Ｃに含まれる各線状伝送部材１１とは異なる色を示す２つの線状伝送部材１１ｅが含まれている。線状伝送部材１１ｅが示す色は例えば青色である。偏平配線部材１０Ｂには、１つの線状伝送部材１１ｅが含まれてもよいし、３つ以上の線状伝送部材１１ｅが含まれてもよい。
　偏平配線部材１０Ｃには、偏平配線部材１０Ａに含まれる各線状伝送部材１１及び偏平配線部材１０Ｂに含まれる各線状伝送部材１１とは異なる色を示す３つの線状伝送部材１１ｆが含まれている。線状伝送部材１１ｆが示す色は例えば黄色である。偏平配線部材１０Ｂには、３つ未満の線状伝送部材１１ｆが含まれてもよいし、４つ以上の線状伝送部材１１ｆが含まれてもよい。
　ここで、偏平配線部材１０Ａに着目する。図１０の例では、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ｂの線状伝送部材１１ｅと異なる色を示す線状伝送部材１１ｄを含んでいる。これにより、偏平配線部材１０Ａは偏平配線部材１０Ｂと区別することが可能である。したがって、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ａと偏平配線部材１０Ｂとを区別可能な色を示す線状伝送部材１１ｄを含んでいると言える。また、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ｃの線状伝送部材１１ｆと異なる色を示す線状伝送部材１１ｄを含んでいる。これにより、偏平配線部材１０Ａは偏平配線部材１０Ｃと区別することが可能である。したがって、偏平配線部材１０Ａの複数の線状伝送部材１１は、偏平配線部材１０Ａと偏平配線部材１０Ｃとを区別可能な色を示す線状伝送部材１１ｄを含んでいると言える。
　同様にして偏平配線部材１０Ｂに着目すると、図１０の例では、偏平配線部材１０Ｂの複数の線状伝送部材１１は、偏平配線部材１０Ｂと偏平配線部材１０Ａとを区別可能な色を示す線状伝送部材１１ｅを含んでいると言える。また、偏平配線部材１０Ｂの複数の線状伝送部材１１は、偏平配線部材１０Ｂと偏平配線部材１０Ｃとを区別可能な色を示す線状伝送部材１１ｅを含んでいると言える。
　同様にして偏平配線部材１０Ｃに着目すると、図１０の例では、偏平配線部材１０Ｃの複数の線状伝送部材１１は、偏平配線部材１０Ｃと偏平配線部材１０Ａとを区別可能な色を示す線状伝送部材１１ｆを含んでいると言える。また、偏平配線部材１０Ｃの複数の線状伝送部材１１は、偏平配線部材１０Ｃと偏平配線部材１０Ｂとを区別可能な色を示す線状伝送部材１１ｆを含んでいると言える。
　なお、図１０の例において、偏平配線部材１０Ａと偏平配線部材１０Ｂとを区別することに着目すれば、偏平配線部材１０Ａ及び偏平配線部材１０Ｂのどちらか一方に含まれるすべての線状伝送部材１１が同じ色であってもよい。同様に、偏平配線部材１０Ａと偏平配線部材１０Ｃとを区別することに着目すれば、偏平配線部材１０Ａ及び偏平配線部材１０Ｃのどちらか一方に含まれるすべての線状伝送部材１１が同じ色であってもよい。同様に、偏平配線部材１０Ｂと偏平配線部材１０Ｃとを区別することに着目すれば、偏平配線部材１０Ｂ及び偏平配線部材１０Ｃのどちらか一方に含まれるすべての線状伝送部材１１は同じ色であってもよい。
　以上のように、図９及び１０の例では、積層される２つの偏平配線部材１０において、一方の偏平配線部材１０の複数の線状伝送部材１１が、当該一方の偏平配線部材１０と他方の偏平配線部材１０とを区別可能な色を示す少なくとも一つの線状伝送部材１１を含んでいる。これにより、当該２つの偏平配線部材を区別することができる。その結果、複数の偏平配線部材１０の積層工程において複数の偏平配線部材が正確に積み重ねられ得る。例えば、複数の偏平配線部材１０を積み重ねる順番を間違ったり、積み重ねる複数の偏平配線部材１０の種類を間違ったりすることが抑制される。
　また、上記の例のように、積層される２つの偏平配線部材１０において、一方の偏平配線部材１０の複数の線状伝送部材１１が、他方の偏平配線部材１０の複数の線状伝送部材１１の少なくとも一つと異なる色を示す少なくとも一つの線状伝送部材を含んでいる場合には、当該２つの偏平配線部材１０を区別し易くなる。よって、複数の偏平配線部材１０の積層工程において複数の偏平配線部材が正確に積み重ねられ得る。
　また、上記の例のように、積層される２つの偏平配線部材１０において、一方の偏平配線部材１０の複数の線状伝送部材１１が、他方の偏平配線部材１０の複数の線状伝送部材１１のそれぞれと異なる色を示す少なくとも一つの線状伝送部材１１を含んでいる場合には、当該２つの偏平配線部材１０をさらに区別し易くなる。よって、複数の偏平配線部材１０の積層工程において複数の偏平配線部材が正確に積み重ねられ得る。
　なお、偏平配線部材１０に含まれる線状伝送部材１１が示す色の具体例は上記の例に限られない。
　＜偏平配線部材での複数の線状伝送部材の配置について＞
　偏平配線部材１０では、共通の特徴を有する複数の線状伝送部材１１が連続的に並列配置されてもよい。図１１は、偏平配線部材１０において、共通の特徴を有する複数の線状伝送部材１１が連続的に並列配置されている様子の一例を示す概略平面図である。図１１に示される偏平配線部材１０には、径の大きさが異なる複数種類の線状伝送部材１１が含まれる。例えば、偏平配線部材１０には、径が大きい複数の線状伝送部材１１ｇと、径が小さい複数の線状伝送部材１１ｈとが含まれてもよい。この場合、偏平配線部材１０では、径が大きい複数の線状伝送部材１１ｇが連続的に並列配置され、径が小さい複数の線状伝送部材１１ｈが連続的に並列配置される。なお、偏平配線部材１０には、径の大きさが異なる３種類以上の線状伝送部材１１が含まれてもよい。
　図１１の例のように、偏平配線部材１０において、径が同じ複数の線状伝送部材１１が連続的に並列配置される場合には、当該複数の線状伝送部材１１を同時に配策することが可能となる。よって、偏平配線部材１０を作製し易くなる。
　図１２は、偏平配線部材１０において、共通の特徴を有する複数の線状伝送部材１１が連続的に並列配置されている様子の他の一例を示す概略平面図である。図１２に示される偏平配線部材１０には、互いに色が異なる複数種類の線状伝送部材１１が含まれる。言い換えれば、偏平配線部材１０には、絶縁被膜の外周面の色が異なる複数種類の線状伝送部材１１が含まれる。例えば、偏平配線部材１０には、黒色の複数の線状伝送部材１１ｉと、赤色の複数の線状伝送部材１１ｊとが含まれてもよい。この場合、偏平配線部材１０では、図１２に示されるように、複数の線状伝送部材１１ｉが連続的に並列配置され、複数の線状伝送部材１１ｊが連続的に並列配置される。なお、偏平配線部材１０には、黒色及び赤色以外の色を示す線状伝送部材１１が含まれてもよい。また、偏平配線部材１０には、互いに色が異なる３種類以上の線状伝送部材１１が含まれてもよい。
　図１３は、偏平配線部材１０において、共通の特徴を有する複数の線状伝送部材１１が連続的に並列配置されている様子の他の一例を示す概略平面図である。図１３に示される偏平配線部材１０には、芯線の種類が異なる複数種類の線状伝送部材１１が含まれる。例えば、偏平配線部材１０には、芯線の材料が異なる複数種類の線状伝送部材１１が含まれてもよい。例えば、偏平配線部材１０には、芯線がアルミニウムで構成された複数の線状伝送部材１１ｋと、芯線が銅で構成された複数の線状伝送部材１１ｌとが含まれてもよい。この場合、偏平配線部材１０では、複数の線状伝送部材１１ｋが連続的に並列配置され、複数の線状伝送部材１１ｌが連続的に並列配置される。なお、偏平配線部材１０には、芯線がアルミニウム及び銅以外の材料で構成された線状伝送部材１１が含まれてもよい。
　偏平配線部材１０には、芯線の形状が異なる複数種類の線状伝送部材１１が含まれてもよい。例えば、偏平配線部材１０には、芯線が撚り線の複数種類の線状伝送部材１１ｋと、芯線が単線の複数の線状伝送部材１１ｌとが含まれてもよい。また、偏平配線部材１０には、芯線を構成する金属の圧縮率が異なる複数種類の線状伝送部材１１が含まれてもよい。例えば、偏平配線部材１０には、芯線を構成する金属の圧縮率が高い複数種類の線状伝送部材１１ｋと、芯線を構成する金属の圧縮率が低い複数の線状伝送部材１１ｌとが含まれてもよい。また、偏平配線部材１０には、芯線の種類が異なる３種類以上の線状伝送部材１１が含まれてもよい。
　＜偏平配線部材の曲がり部での線状伝送部材の配置について＞
　偏平配線部材１０が、複数の線状伝送部材１１が曲がる曲がり部１００を備える場合には、曲がり部１００では、最小径の線状伝送部材１１が最も内側に位置してもよい。曲がり部１００には、偏平配線部材１０が備える複数の線状伝送部材１１のすべてが含まれてもよいし、当該複数の線状伝送部材１１の一部だけが含まれてもよい。
　図１４は曲がり部１００の一例を示す概略平面図である。図１４の例では、偏平配線部材１０の曲がり部１００には、湾曲する線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐが含まれる。線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐの径はこの順で大きくなっている。曲がり部１００では、最小径の線状伝送部材１１ｍが最も内側に位置している。そして、曲がり部１００では、径が大きいほど外側に位置するように線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐが配置されている。よって、最大径の線状伝送部材１１ｐは最も外側に位置する。
　このように、曲がり部１００では、複数の線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐのうち最小径の線状伝送部材１１ｍが最も内側に位置する。これにより、線状伝送部材１１ｍよりも外側の径が大きい線状伝送部材１１ｎ，１１ｏ，１１ｐの曲げ半径を大きくすることができる。径が大きい線状伝送部材１１ｎ，１１ｏ，１１ｐの曲げ半径を大きくすることによって、径が大きい線状伝送部材１１ｎ，１１ｏ，１１ｐが曲げ易くなる。よって、曲がり部１００を有する偏平配線部材１０を作製し易くなる。
　また、図１４の例のように、曲がり部１００において、径が大きいほど外側に位置するように複数の線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐが配置される場合、曲がり部１００では、線状伝送部材１１の径が大きいほど、線状伝送部材１１の曲げ半径を大きくすることができる。よって、複数の線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐが曲げ易くなる。
　また、曲がり部１００において、径が大きいほど外側に位置するように複数の線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐが配置される場合には、図１４に示されるように、曲がり部１００において、複数の線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐをつめて配置し易くなる。これにより、曲がり部１００が占めるスペースを小さくすることができる。よって、偏平配線部材１０の配策スペースを小さくすることができる。
　なお、偏平配線部材１０の曲がり部１００には、径が同じ複数の線状伝送部材１１が含まれてもよい。例えば、曲がり部１００に複数の線状伝送部材１１ｍが含まれる場合には、複数の線状伝送部材１１ｍは最も内側から外側にかけて連続的に並列配置される。また、曲がり部１００に複数の線状伝送部材１１ｐが含まれる場合には、複数の線状伝送部材１１ｐは最も外側から内側にかけて連続的に並列配置される。
　また、複数の線状伝送部材１１ｍ，１１ｎ，１１ｏ，１１ｐのうち、最小径の線状伝送部材１１ｍ以外の線状伝送部材１１についての曲がり部１００での配置位置は図１４の例に限られない。例えば、線状伝送部材１１ｏを曲がり部１００の最も外側に配置してもよい。また、線状伝送部材１１ｏを線状伝送部材１１ｍの隣に配置してもよい。
　また、配線部材１の積層部分２が、線状伝送部材１１の長手方向に沿って曲がる曲がり部２００を備える場合には、曲がり部２００において、最小径の線状伝送部材１１を備える偏平配線部材１０を最も内側に配置してもよい。
　図１５は配線部材１の積層部分２の一例を示す概略断面図である。図１５の例では、偏平配線部材１０Ａ，１０Ｂ，１０Ｃのそれぞれは、同じ径の複数の線状伝送部材１１を備えている。また、偏平配線部材１０Ａ，１０Ｂ，１０Ｃの間では、線状伝送部材１１の径が異なっている。偏平配線部材１０Ａは最小径の線状伝送部材１１ｑを備える。偏平配線部材１０Ｂは、２番目に径が小さい線状伝送部材１１ｒを備える。偏平配線部材１０Ｃは最大径の線状伝送部材１１ｓを備える。
　図１６は、図１５に示される積層部分２が備える曲がり部２００の一例を示す概略側面図である。図１６に示される曲がり部２００では、最小径の線状伝送部材１１ｑを備える偏平配線部材１０Ａが最も内側に位置する。また、曲がり部２００では、径が２番目に小さい線状伝送部材１１ｒを備える偏平配線部材１０Ｂが真ん中に位置する。そして、曲がり部２００では、最大径の線状伝送部材１１ｓを備える偏平配線部材１０Ｃが最も外側に位置する。
　このように、曲がり部２００では、最小径の線状伝送部材１１ｑを備える偏平配線部材１０Ａが最も内側に位置する。これにより、線状伝送部材１１ｑよりも外側の径が大きい線状伝送部材１１ｒ，１１ｓの曲げ半径を大きくすることができる。径が大きい線状伝送部材１１ｒ，１１ｓの曲げ半径を大きくすることによって、径が大きい線状伝送部材１１ｒ，１１ｓが曲げ易くなる。よって、曲がり部２００を有する配線部材１を作製し易くなる。
　また、図１６の例のように、曲がり部２００において、偏平配線部材１０が備える線状伝送部材１１の径が大きいほど偏平配線部材１０が外側に位置する場合、線状伝送部材１１の径が大きいほど線状伝送部材１１の曲げ半径を大きくすることができる。よって、複数の線状伝送部材１１ｑ，１１ｒ，１１ｓが曲げ易くなる。
　なお、曲がり部２００には、線状伝送部材１１の径が同じである複数の偏平配線部材１０が含まれてもよい。例えば、曲がり部２００に、それぞれが線状伝送部材１１ｑを備える複数の偏平配線部材１０Ａが含まれる場合には、複数の偏平配線部材１０Ａは最も内側から外側にかけて連続的に配置される。また、曲がり部２００に、それぞれが線状伝送部材１１ｓを備える複数の偏平配線部材１０Ｃが含まれる場合には、複数の偏平配線部材１０Ｃは最も外側から内側にかけて連続的に配置される。
　また、偏平配線部材１０Ａ，１０Ｂ，１０Ｃのうち、最小径の線状伝送部材１１ｑを備える偏平配線部材１０Ａ以外の偏平配線部材１０についての曲がり部２００での配置位置は図１６の例に限られない。例えば、偏平配線部材１０Ｂは、曲がり部２００の最も外側に設けられてもよい。
　以上のように、配線部材１は詳細に説明されたが、上記した説明は、全ての局面において例示であって、この開示がそれに限定されるものではない。また、上述した各種変形例は、相互に矛盾しない限り組み合わせて適用可能である。そして、例示されていない無数の変形例が、この開示の範囲から外れることなく想定され得るものと解される。
