Loops of the primary coil and the secondary coil group are along a surface of the printed circuit board. The rotary plate includes a target portion whose outer circumferential edge portion has a sine-wave shape. The primary coil overlaps with the target portion, and has a circular-arc shape along a rotational direction of the rotary plate. The secondary coil group includes 4n (n is a natural number) secondary coils arranged in a line along the rotational direction, on an inner circumferential side of the primary coil. The number of turns of a secondary coil on an end side in a line is smaller than that of a secondary coil on an inner side in the line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotational angle sensor","description":"A rotational angle sensor includes a rotary plate and a printed circuit board in which a primary coil and a secondary coil group are arranged.
