<p>PURPOSE: A circuit board and a method for mounting air core coil are provided to reduce the height of an air core coil mounted on a circuit board having a coil mounting portion by accommodating a first lead portion and a second lead portion of the air core coil in the coil mounting portion. CONSTITUTION: An air core coil(1) is embedded in an opening(51) of a circuit board(50). The opening accommodates the air core coil. A through-hole(52) is formed at the upper portion of the circuit board. A central conductive connector of a connecting component of the antenna input terminal is received in the though-hole. A conductive part(53) is formed at the peripheral area of the circuit board. At the left side of the through-hole, a through-hole(54a) and a through-hole(54b) are formed for ground potential connections. At the right side of the through-hole(54a) formed at the left side of the through-hole, a conductive part(55) for a capacitor of a HPF(High-path filter) is formed.
