<p>PROBLEM TO BE SOLVED: To provide an ignition coil device for internal combustion engine, where the quantity of insulating resin filled in a case body, is reduced to make the device lighter, without deteriorating magnetic coupling of a crosswise iron core. SOLUTION: As a main constitution, there are disposed a case body 75 with an open top surface which is molded and fixed by injecting an insulating resin onto a densely engaged coil body 4a, a first crosswise iron core 5 on which first connecting parts 76 are formed, so as to hold the lower part side of the case body 75 and a second crosswise iron core 6 on which second connecting parts 77 are formed so as to hold the top part side. In this state, connecting tools 92 are inserted from second through-holes 86 to first through-holes 83 to be connected to a predetermined position of an internal combustion engine, so that the first crosswise iron core 5 and the second crosswise iron core 6 are connected.</p> |
