    • A microwave strip line filter has a pair of dielectric substrates being stacked and bonded to each other, which are similar in pattern but different in dimension. The dielectric substrates are bonded to each other with spots of bonding agent applied to resonant electrodes on one of the dielectric substrates, thereby preventing the electric characteristic from being adversely affected by bonding agent when the dielectric substrates are superimposed and bonded to each other. The dielectric substrates are made of ceramic materials having relative dielectric constants in order to easily and exactly obtain various desirable resonant frequency characteristics by using resonant electrodes having the same pattern.
