Provided is an inductively coupled plasma generation device capable of having both a wide matching range and reduced loss. An inductively coupled plasma generation device in which high harmonic waves from a high harmonic wave power source (11) are supplied to an antenna (14) by way of a matching device (12) which matches impedance, and plasma is generated in a vacuum vessel by electromagnetic waves from the antenna (14), wherein an L-type matching circuit is used as the matching device (12) and a capacitor (C3) is provided parallel to the antenna (14) at a position closer to the antenna (14) than capacitors (C1, C2) in the L-type matching circuit.
