Abstract
In a case where first wirings (wirings for a driving power supply (VH)) commonly connected to a plurality of electro-thermal converting elements and adapted to supply an electric power to the plurality of electro-thermal converting elements and second wirings (high voltage grounding wirings (GNDH)) for connecting source areas of respective switching elements to grounding potential are provided, resistance of the second wiring is selected to be smaller than resistance of the first wiring.
