在该电线束中，
在所述电连接器内收容电气基板，
所述多根电线分为在一个平面上排列的第一组、和在与所述第一组的并列面不同的一个平面上排列的第二组，
包含于所述第一组的所述多根电线中的与所述电气基板连接的部位的附近部分利用第一树脂模保持，并且包含于所述第二组的所述多根电线中的与所述电气基板连接的部位的附近部分利用第二树脂模保持。
根据该结构，容易进行末端加工时的电线的区分。
(2)优选利用所述第一树脂模排列保持的电线连接于所述电气基板的第一主表面，利用所述第二树脂模排列保持的电线连接于所述电气基板的所述第一表面的背侧即第二主表面。
根据该结构，在电气基板的两主表面设置有连接端子的情况下，能够提高用于将电线与电气基板的两主表面的各连接端子连接的作业效率。另外，按照每个线种类能够在与各树脂模相比的线缆的端部侧将各电线的长度设为所需最小限，因此不易引起电线的前端部的排列间距的偏移，能够按照电线的每个线种类维持电线的排线精度。
(3)优选所述第一树脂模以及所述第二树脂模的侧表面与所述电气基板的侧表面接触，以使得从所述电气基板的厚度方向的中心面、至所述第一树脂模以及所述第二树脂模的与所述中心面接近侧的主表面为止的距离彼此相等。
根据该结构，能够将从第一树脂模以及第二树脂模的(电气基板23侧)的侧表面分别伸出的同轴电线以及绝缘电线的长度缩短。因此，对电线弯曲而使电线端(中心导体)不能位于作为连接对象的电气基板的连接端子上的情况进行抑制。由此，不需要进行修正电线的弯曲的作业，将电线与基板的连接端子连接的作业变得容易。
(4)优选在从所述外皮的端部至所述第一树脂模以及所述第二树脂模为止之间，所述多根电线露出。
在使电线从外皮的端部伸出而分为两组时，需要使电线弯曲，但根据上述结构，能够在电线的露出部处弯曲电线。另外，通过在第一树脂模以及第二树脂模和外皮之间形成电线的露出部，从而能够将各树脂模容易地配置在电气基板的上表面侧和下表面侧。
(5)优选利用所述第一树脂模排列保持的电线与利用所述第二树脂模排列保持的电线是不同的电线种类。
根据该结构，同种类的电线在电气基板的相同面侧汇集，因此各电线的末端加工变得容易，能够提高作业效率。
(6)优选利用所述第一树脂模排列保持的电线是同轴电线，利用所述第二树脂模排列保持的电线是绝缘电线。
(7)优选利用所述第一树脂模排列保持的电线是屏蔽双绞(STP)线，利用所述第二树脂模排列保持的电线是绝缘电线。
(8)优选利用所述第一树脂模排列保持的电线是双芯平行电线(Twinax)，利用所述第二树脂模排列保持的电线是绝缘电线。

如图2(b)所示，各同轴电线15具有中心导体16、包覆中心导体16的绝缘体17、在绝缘体17的外侧配置的外部导体18、以及包覆外部导体18的外皮19。在本实施方式中，同轴电线15例如是以2根为一对发送和接收高速差分信号的高速差分信号线。一对同轴电线15可以是对绞线，也可以不是绞线。作为由一对同轴电线15构成的同轴电线对，在本例子中例如四对同轴电线对15A、15B、15C、15D收容在线缆11内。
图3是表示同轴电线15以及绝缘电线50的前端部连接于第一连接器21内的电气基板23的状态的俯视图。图4是图1示出的第一连接器21的IV-IV线剖视图。
如图3及图4所示，在线缆11的端部处护套12等被去除而将同轴电线15以及绝缘电线50露出。从线缆11露出的多根同轴电线15以在一个平面上并列的状态，其露出部分的一部分(多根同轴电线15中的与电气基板23连接的部位的附近部分)被第一树脂模26A树脂封装。另外，多根绝缘电线50在多根同轴电线15的并列面的下侧以在一个平面上并列的状态，其露出部分的一部分(多根绝缘电线50中的与电气基板23连接的部位的附近部分)被第二树脂模26B树脂封装。从线缆11的护套12的端部至第一树脂模26A以及第二树脂模26B为止之间同轴电线15以及绝缘电线50露出，在该部分处电线15、50弯曲，第一树脂模26A和第二树脂模26B沿电气基板23的厚度方向重叠。此外，在护套12的内侧存在集中屏蔽层的情况下，通过去除集中屏蔽层或者向护套12上方折回，从而将电线15、50在从护套12的端部至第一树脂模26A和第二树脂模26B为止之间露出。
在各同轴电线15的与利用第一树脂模26A进行树脂封装后的部分相比的前端侧，从外皮19依次露出外部导体18、绝缘体17以及 中心导体16。另外，在绝缘电线50的与利用第二树脂模26B进行树脂封装后的部分相比的前端侧，从外皮52露出中心导体51。
在电气基板23的上表面23A，沿着与线缆11连接一侧的端缘并列配置有多个第一连接端子30A。在与第一连接端子30A相比更接近端缘侧处，与第一连接端子30A的并列方向平行地配置有长条状的接地用连接端子30C。另外，在电气基板23的下表面23B，沿着与线缆11连接一侧的端缘并列配置有多个第二连接端子30B。此外，第二连接端子30B的配置结构与第一连接端子30A相同，是将大于或等于绝缘电线的数量的端子并列的结构。
在利用第一树脂模26A排列保持的各同轴电线15的前端部处露出的中心导体16，例如通过软钎焊与上表面23A侧的第一连接端子30A连接。另外，外部导体18通过软钎焊与上表面23A侧的接地用连接端子30C连接。
另一方面，在利用第二树脂模26B排列保持的各绝缘电线50的前端部处露出的中心导体51，例如通过软钎焊与下表面23B侧的第二连接端子30B连接。
而且，在各同轴电线15以及各绝缘电线50与电气基板23的各连接端子30A、30B连接的状态下，利用第三树脂模27树脂封装了电气基板23的上表面23A以及下表面23B和同轴电线15以及绝缘电线50的周围。
在利用第三树脂模27进行树脂封装后的电气基板23的一端侧配置有连接器插头24。省略连接器插头24的内部结构的详细说明，在连接器插头24的内部设置有多个接触销(省略图示)。接触销在电气基板23的端部(与连接线缆11的一侧相反的端部)与电气基板23上的电路连接。即，线缆11和接触销成为经由电气基板23连续的导电电路。
而且，直至连接器插头24的另一端侧的一部分、电气基板23以及线缆11的护套12前端部，利用第四树脂模28树脂封装了第一连接器21整体。如图1及图4所示，在第四树脂模28的另一端侧，用于降低向线缆11的应力的树脂制应变消除部29包覆在护套12的周 围。
根据以上说明的本实施方式所涉及的电线束10，在一个平面上排列的多根同轴电线15中的与电气基板23连接的部位的附近部分，利用第一树脂模26A进行了保持，并且在与多根同轴电线15的并列面不同的一个平面上排列的多根绝缘电线50中的与电气基板23连接的部位的附近部分，利用第二树脂模26B进行了保持。将在线缆11的端部处露出的多根同轴电线15利用第一树脂模26A集中保持，并且将多根绝缘电线50利用第二树脂模26B集中保持，从而能够容易地进行各电线15、50的末端加工时的区分。另外，将电线15、50分为了两组，因此各组的宽度变窄。
另外，利用第一树脂模26A排列保持的多根同轴电线15与电气基板23的上表面23A侧的第一连接端子30A连接，并且利用第二树脂模26B排列保持的多根绝缘电线50与电气基板23的下表面23B侧的第二连接端子30B连接。根据该结构，在电气基板23的两面连接电线15、50时，能够将连接在各面上的电线15、50汇总，而从电气基板23的上下进行电线15、50和电气基板23(的连接端子)之间的连接加工，因此加工变得容易。另外，同种类的电线(同轴电线15彼此、绝缘电线50彼此)在电气基板23的相同面侧汇集，而与电气基板23上的连接端子30A、30B连接，因此将同轴电线15以及绝缘电线50与各连接端子30A、30B连接时的各电线15、50的末端加工变得容易，能够提高制造效率。而且，同轴电线15以及绝缘电线50按照每个线种类进行汇总，并利用树脂模26A、26B分别进行树脂封装，从而能够在与树脂模26A、26B相比的线缆11的端部侧将各电线15、50长度设为所需最小限。例如，如图4所示，绝缘电线50与同轴电线25相比容易将从模体伸出的部分的长度加工得较短。由此，不易引起电线15、50的前端部的排列间距的偏移，能够分别维持同轴电线15的排线精度以及绝缘电线50的排线精度。
优选使利用树脂模26A、26B进行树脂封装后的部分位于电气基板23之外。由此，在电气基板23上仅配置从树脂模26A、26B伸出的各电线15、50，因此能够将连接端子30A、30B尽可能地配置 在电气基板23的端部侧。树脂模26A、26B不会碰到电气基板23，因此在图4中观察时能够将从各电线15、50至连接端子30A、30B为止的上下方向的距离设为最小。由此，能够在电气基板23上减小为了使电线15、50向电气基板23接近而弯曲的量。
另外，如图5所示，优选使第一树脂模26A以及第二树脂模26B的侧表面26A1、26B1与电气基板23的侧表面23C接触地配置，以使得从电气基板23的厚度方向的中心面C至第一树脂模26A以及第二树脂模26B的主表面(与中心面C接近侧的主表面)26A2、26B2为止的距离彼此相等。即，第一树脂模26A以及第二树脂模26B配置为，使得从中心面C至第一树脂模26A的单侧的主表面26A2为止的距离LA、和从中心面C至第二树脂模26B的单侧的主表面26B2为止的距离LB相等。如果树脂模与电气基板远离，则不得不与其远离量对应地将电线露出得较长，通过设为图5所示的结构，从而能够将从第一树脂模26A以及第二树脂模26B分别伸出的电线15、50的长度缩短(设为最小)。由此，能够防止下述情况，即，电线15、50弯曲而使电线端(中心导体16、51)不能位于作为连接对象的电气基板23的连接端子30A、30B上。
以上将本发明使用其实施方式进行了说明，但本发明的技术范围并不限定于上述实施方式记载的范围。对于本领域的技术人员而言，显然可以对上述实施方式进行多种变更或改良。
在上述实施方式的电线束10中，示出在线缆11中包含同轴电线15和绝缘电线50的例子，但并不限定于该例子。例如，也可以构成为，线缆包含多根屏蔽双绞线(STP；带屏蔽双绞线)和多根绝缘电线(各线没有绞合的离散线)，将多根STP线利用树脂模集中地排列保持，并且将多根绝缘电线利用与STP线不同的树脂模集中地排列保持。另外，也可以构成为，线缆包含多根双芯平行电线(Twinax)和多根绝缘电线(各线没有绞合的离散线)，将多根双芯平行电线利用树脂模集中地排列保持，并且将多根绝缘电线利用与双芯平行电线不同的树脂模集中地排列保持。双芯平行电线是指，在双芯平行的信号线上将金属树脂带等以螺旋状卷绕的电线。
另外，在上述实施方式的电线束10中，说明了在线缆11的两端安装的第一连接器21的连接器插头24和第二连接器22的连接器插头24为相同形状的情况，但也可以将两端的连接器插头的形状不同的电连接器安装在线缆的两端。
