PROBLEM TO BE SOLVED: To provide an antenna loading coil of an AM receiver that can increase sensitivity in the AM receiver easily, miniaturizes the AM receiver by reducing the number of components to be used, and can reduce costs. SOLUTION: There are a metal case 6, first wiring 4 wound around a winding groove on a drum-shaped core 1 having two winding grooves divided by a collar 1b, and second wiring 5 wound around a lower winding groove. A pot core 2 is arranged while wrapping the first wiring. The first wiring is set to be the antenna loading coil. The second wiring is set to be an FM band isolation coil.
