|Applicants:||SUMITOMO ELECTRIC PRINTED CIRCUITS, INC.
|Title:||FLEXIBLE PRINTED CIRCUIT BOARD FOR SOLENOID COIL, SOLENOID COIL, AND WEARABLE DEVICE|
A flexible printed circuit board for a solenoid coil, the flexible printed circuit board comprising: an insulating film; a conductive pattern that is laminated on at least one surface side of the insulating film; a coil region; and a connection region. The coil region includes n (n being at least 2) wires that constitute the conductive pattern and that are provided in stripes along the length direction. The connection region extends from the coil region along a first side-edge direction of the coil region from a first side-edge-side end part of a connection-region-extension side edge of the coil region. The connection region has n wires that constitute the conductive pattern and that are continuous from the n wires of the coil region.
