A solenoid coil unit is provided with: solenoid coils provided parallel to other solenoid coils at a predetermined spacing distance in an isolation direction orthogonal to a central axis direction; and a rod-shaped iron core on which the solenoid coil is wound, the rod-shaped iron core being longer than the length of the solenoid coil in the central axis direction. The rod-shaped iron core is provided with a central part for winding the solenoid coil and end parts which are positioned at two ends of the rod-shaped iron core and extend out from two ends of the solenoid coil; the ratio of the length to the width of the central part is 2 or more; the length of the solenoid coil in the central axis direction is approximately twice the spacing distance.
一种螺线管线圈单元,其具备:螺线管线圈,相对于其他的螺线管线圈平行地设置成沿着与中心轴方向正交的隔离方向隔着预定的间隔距离;以及棒状铁心,供所述螺线管线圈卷绕,且比所述螺线管线圈的所述中心轴方向的长度还长。所述棒状铁心具有供所述螺线管线圈卷绕的中央部、以及位于所述棒状铁心的两端且从所述螺线管线圈的两端延伸出的端部;所述中央部的长度对宽度的比例为2以上;所述螺线管线圈的所述中心轴方向的长度为所述间隔距离的大致二倍。
