An internal combustion engine ignition device includes; a transformer including a primary coil and a secondary coil that are electromagnetically coupled; an energization control unit that controls energization of the primary coil; a first spark plug electrically connected between a high-voltage terminal of the secondary coil and ground; and a second spark plug electrically connected between a low-voltage terminal of the secondary coil and the ground. The first spark plug and the second spark plug are placed in one same combustion chamber of an internal combustion engine. Thus, discharge occurs in the two spark plugs, so that a fuel can be more certainly ignited. Further, residual energy of the first spark plug and residual energy of the second spark plug offset each other, which enables rapid convergence of residual energy.
