    • The differences in characteristics among parts or the fluctuations of the inductance value of a coil due to temperature variation is lessened by reducing the stray capacitance components induced among the layers of wound conductor, and size reduction and cost reduction are achieved. A winding portion (30) between two flange portions (22a, 22b) is divided into a plurality of sections (30a, 30b, 30c, 30d). One layer of conductor is wound from one end to the other end in each section, and then layers of conductor are wound in the alternately reversed directions to form the multilayer winding portion (30) by solenoid winding. The conductor is preferably wound in such a way that the boundary surface between adjacent sections inclines to a flange portion, which is the winding start, and the boundary surface of an upper layer is closer to the flange portion than that of a lower layer. Further the conductor is preferably wound in such a way that at least portions near upper layers of end faces facing the flange portions are apart from the flange portions so as to be farther from the flange portions than lower layers of the end faces in each section at both ends. This divided solenoid winding coil can be used for an antenna coil or a transformer coil.
    • 通过减少在卷绕导体层之间引起的杂散电容成分,可以减少部件之间的特性差异或由于温度变化导致的线圈的电感值的波动,从而实现尺寸减小和成本降低。 两个凸缘部分(22a,22b)之间的缠绕部分(30)被分成多个部分(30a,30b,30c,30d)。 在每个部分中,从一端到另一端缠绕一层导体,然后在交替反向的方向上卷绕导体层,通过螺线管绕组形成多层缠绕部分(30)。 导体优选地以相邻部分之间的边界面倾斜到作为卷绕开始的凸缘部分的方式缠绕,并且上层的边界表面比下层更靠近凸缘部分。 此外,导体优选地以这样的方式缠绕,使得靠近凸缘部分的端面的上层附近的至少部分与凸缘部分分离,以便比每个部分中的端面的下层更远离凸缘部分 两端 该分割的电磁线圈绕组线圈可用于天线线圈或变压器线圈。

    • An antenna device includes: a winding component having an approximately cylindrical shaped winding shaft portion and a flange portion disposed to project outside the winding shaft portion in at least one end portion of both end portions in an axial direction of the winding shaft portion; a pair of binding terminals disposed to project outside the flange portion in at least one of the flange portions; and a winding both ends of which are bound to the pair of binding terminals. The flange portion on which the binding terminals are disposed has an approximate disk shape. At least one binding terminal is disposed to be oriented along a direction approximately perpendicular to an outer periphery of the flange portion on which the binding terminal is disposed.
    • 天线装置包括:绕组部件,其具有近似圆筒形的卷绕轴部分和凸缘部分,所述凸缘部分设置成在卷绕轴部分的轴向方向上在两个端部的至少一个端部中突出到卷绕轴部分的外侧; 一对装订端子,设置成在至少一个所述凸缘部分中突出到所述凸缘部分外部; 并且其两端的绕组绑定到所述一对装订端子。 设置有装订端子的凸缘部分具有近似盘形。 至少一个装订端子设置成沿着大致垂直于布置有装订端子的凸缘部分的外周的方向定向。
