PROBLEM TO BE SOLVED: To obtain a full ignition output by reducing leakage flux in constituting an ignition magneto which utilizes the rotor magnet of a main generator. SOLUTION: A window 1A is formed on a surrounding wall 1a of a rotor yoke 1, and the one of permanent magnets M1 fixed to the inner surface of the surrounding wall 1a is attached to the inner side of the window. The thickness of a middle part mc of the magnet M1 is formed larger than the thickness of both wing parts ma and mb, the middle part mc is arranged inside a window 1A, and the both wing pats ma and mb touch on the inner sides of the parts along a pair of the opposing sides of the window 1A. The magnetic pole surface on the outer circumference side of the middle part mc of the magnet M1 is positioned on the same surface with the outer circumference of the surrounding wall of the rotary yoke 1, and a magnetic pole 5a of the core of an ignition coil 7 is made to face with a three pole ignition magnetic field of the magnet, comprising the magnet M1 and magnetic poles which appear on the outer surface of the surrounding wall on the both sides of the window 1A.
