PURPOSE:To easily form a bypass capacitor or a coupling capacitor coping with high density mount. CONSTITUTION:A strip conductor 3 is provided in a dielectric body 2 of a multi-layer board and an interval between ground planes 1a and 1b opposite to the strip conductor 3 is changed and the area of the strip conductor 3 is changed to form a capacitor with a prescribed static capacitance between the strip conductor 3 and the ground planes 1a, 1b. One terminal of the strip conductor 3 is connected to a power line of the high frequency circuit with a throughhole to act the capacitor like a bypass capacitor. Moreover, a surface mount component is connected by the strip conductor 3 and the ground planes 1a, 1b with a throughhole to act the capacitor like a coupling capacitor and other component is mounted between the components on the surface to attain high density mount. |
