A high frequency filter in combination with an internal electronic circuit element of the flat-plate type, such as a hybrid integrated circuit element contained within a casing, includes an electrode member arranged on a circuit board within the casing to be grounded, an insulation substance layer, integrally formed on the electrode member and being made of a dielectric material whose dielectric constant decreases or increases in accordance with an increase or a decrease of wireless frequency applied thereto, and an electrode strip integrally formed on the insulation substance layer for connection to an external electric circuit. The internal electronic circuit element is integrally provided on either the electrode member or the insulation substance layer and connected to the electrode strip, and the electrode member is mounted on the circuit board to carry the electronic circuit element in place.
