To provide a plasma type ignition device superior in durability by suppressing wear of a cathode due to sputtering of the cathode.

In the plasma type ignition device 1 to carry out ignition of an internal combustion engine, a discharge distance fixing member 120, which is constructed of a conductive material supplementing part 121 consisting of a conductive material capable of melting by heat from plasma-state gas and a conductive material supplemented part 122 receiving supplement of the conductive material, is formed so as to cover the surface of a cathode 110 in order to prevent discharge distance fluctuations due to wear of the cathode 110 caused by collision of the plasma-state gas, and discharge is made to carry out between the surface of the discharge distance fixing member 120 and an anode 154.
