Abstract: A switching circuit apparatus includes: a first capacitance provided between a first port terminal and a the first terminal of a switching circuit unit, a second capacitance provided between the first terminal and a conductor part, and a first inductance provided between a second port terminal and a second terminal of the switching circuit unit. The switching circuit apparatus is provided with: a first capacitor connected between the first port terminal and the second port terminal, and a second inductor connected between the second terminal and the conductor part. The second inductor has such an inductance that a ratio of the inductance of the second inductor to the first inductance is equal to a ratio of the first capacitance to the second capacitance.
