Provided is a plasma generation device that can suppress arc discharge in which discharge is localized and that produces high temperatures, and that can generate atmospheric-pressure discharge plasma highly efficiently, stably, and without spatial deviation, and at a low temperature of roughly room temperature. The plasma generation device has a plurality of opposing electrodes, wherein provided is a discharge position control means which is disposed between the plurality of electrodes and which is formed with an inverse characteristic material housed in a vessel that is made of a dielectric substance, the inverse characteristic material comprising a fluid that is characterized in that in accordance with a rise in temperature the dielectric constant decreases and that also has polarizability. The inverse characteristic material is spaced apart from the plurality of electrodes.
