An electronic device is provided to easily recognize an image of a conductive pattern by increasing a light reflexibility of a conductive pattern. An electronic device includes a substrate(25), a plurality of coils(10,20), a conductive pattern(50a), and a capacitor. A coil of a spiral shape is installed on the substrate. The conductive pattern is formed in an inner side of the coil. A light reflexibility of the conductive pattern is higher than a light reflexibility of a surface of the coil. The conductive pattern is divided, and is a marker for checking a position or a pattern for recognizing an image. A shape of the conductive pattern is one among circular, square, triangle, diamond, and oval shape. The capacitor is installed on the substrate. The conductive pattern is made of material such as a bottom electrode of the capacitor. |
