    摘要: An electronic device includes a substrate, two ellipse spiral coils that are provided on the substrate, are spaced from each other in a longitudinal direction thereof, and are electrically connected to each other, two wires that are electrically connected to outermost circumference of the two coils respectively and extract the two coils to outside, and a connection portion that electrically connects each end of innermost circumference of the two coils. A ratio of inner diameter against outer diameter of the two coils in a long axis direction and in a short axis direction thereof is respectively 0.5 to 0.8.
