PROBLEM TO BE SOLVED: To provide a high frequency circuit for preventing production of an output loss due to a mismatching loss even when a high frequency signal passes over between boards. SOLUTION: The high frequency circuit is characterized in that a first high frequency circuit board 21 and a second high frequency circuit board 22 are connected by using a copper foil 3 subjected to forming in a manner that the characteristic impedance (Z<SB>s</SB>) of the parts of the copper foil 3 existing on the boards is the same as the characteristic impedance (Z<SB>0</SB>) of the part of the copper foil 3 existing in a space (between the copper foil and a seating).
