PROBLEM TO BE SOLVED: To suppress a yield decrease in a manufacturing process of recording heads even when a chip size is increased due to a great increase of the number of heating elements to be set on one substrate. SOLUTION: An inkjet recording head with a plurality of the heating elements, a plurality of driving circuits for driving each heating element, and a logic circuit for selectively operating the driving circuits by a predetermined sequence discharges ink by utilizing a heat energy generated from the heating elements. Each driving circuit is configured to include a plurality of switch elements (T1-T10) connected in parallel. COPYRIGHT: (C)2005,JPO&NCIPI
