A resonator pattern made of superconductive material is disposed over a
first surface of a base substrate made of dielectric. An adjustment
substrate made of dielectric is disposed facing the first surface at a
distance from the first surface. The adjustment substrate is supported by
a support mechanism for supporting the adjustment substrate in such a
manner capable of changing an angle between the first surface and a
surface of the adjustment substrate facing the base substrate. A
superconductive filter is provided which can shift a center frequency of
a filter band and suppress disturbance of a waveform of a filter
characteristic, with a simple method.
