PROBLEM TO BE SOLVED: To provide a mounting structure for a plasma ignition device, fixing the plasma ignition device in a mounting hole with injection holes of the plasma ignition device oriented to desired directions without using components separated from the plasma ignition device. SOLUTION: In the mounting structure for the plasma ignition device gripping a flange 6a of the plasma ignition device 100 by a pressing surface 9b of a pipe member 9 including an outside screw 9a meshing with the internal screw 201a of the mounting hole 201 and the step 201b of the mounting hole, and fixing the plasma ignition device in the mounting hole with the injection holes 5 oriented to the desired directions, a stopper 10 retaining the pipe member rotatably around the plasma ignition device between the plasma ignition device and the flange part is provided on the plasma ignition device, and the flat surface formed on an outer circumference surface of the stopper part functions as a retention surface retaining the injection holes toward the desired directions while the pipe member is screwed in the mounting hole.
