Claim 0:
1. An ink jet printing system comprising:
an electromagnetic wave generator including
an electromagnetic wave generation section that generates an electromagnetic wave,
a high-frequency voltage generation section that generates a voltage applied to the electromagnetic wave generation section, and
a transmission line that electrically couples the electromagnetic wave generation section and the high-frequency voltage generation section to each other in which
the electromagnetic wave generation section includes a first electrode, a second electrode, a first conductor that electrically couples the first electrode and the transmission line to each other, and a second conductor that electrically couples the second electrode and the transmission line to each other,
one of the first electrode or the second electrode is a reference potential electrode to which a reference potential is applied and the other is a high-frequency electrode to which a high-frequency voltage is applied, and
the first conductor further includes a coil, and the coil is disposed at a position closer to the first electrode than the transmission line, and
a substrate; and
an ink jet head discharging ink, wherein
the first electrode and the second electrode are formed above the substrate.
