PROBLEM TO BE SOLVED: To prevent the temperature of an ink in an applicable liquid supply port array of a liquid discharge board having a plurality of liquid supply ports and maintain the quality of printing even in high duty continuous printing. SOLUTION: The liquid discharge head has heat dissipation bumps 23 provided in areas between adjacent ink supply ports of the liquid discharge board 2 and conductors 13 formed in the face of a support member 1 of an alumina laminate wiring structure facing the areas. When the liquid discharge board 2 is supported on the support member 1, the heat dissipation bumps 23 contact the conductors 13. COPYRIGHT: (C)2008,JPO&INPIT
