A high frequency power distribution device includes: a distribution member for uniformly dividing a high frequency power into divided high frequency powers; coaxial transmission lines through which the divided high frequency powers are introduced to the parallel plate electrodes; and an impedance control mechanism which controls an input impedance to decrease a current value. The distribution member includes: a high frequency power input unit for inputting the high frequency power to an input point; and a plurality of high frequency power output units spaced from each other at a regular interval, and each of the coaxial transmission lines are connected to one of the high frequency power output units, and the impedance control mechanism is provided at the high frequency power input unit. |
