Abstract
An ignition device is provided, the ignition device comprises a coaxial structural body comprising an inner conductor, an outer conductor, and an insulatorthat insulates both the conductorsand, which are coaxially provided with one another along an axial direction. A connection terminalis arranged at one axial end side of the coaxial structural body and connecting the inner conductorand the outer conductorto the electromagnetic wave oscillator MW. The inner conductorhas a linearly extended part protruding at another axial end side of the coaxial structural body extending outwards from the outer conductorin the axial direction and a spirally extended part continuously extending from the linearly extended part in a reversed direction and in a spiral manner that winds around the linearly extended part of the inner conductorin a predetermined number of turns around the linearly extended part such that the inner conductorforms a resonance structure and the spirally extended partwith the resonance structure is obtained. A diameter and a length of the inner conductorthat is extended outwards from the outer conductor, and the number of turns of the spirally extended part of the inner conductorare determined such that a capacitive reactance XC and an inductive reactance XL of the spirally extended part are substantially equal to each other.
