Abstract
A liquid ejection print head includes a base accommodated in a frame and having electrothermal transducers supplied with energy from an external source for having liquid to eject the liquid to effect printing, a conductive layer for forming an electrical wiring, and a tape member for supporting the conductive layer. The tape member has connecting portions, which include (i) branch portions, which are electrically connected to the transducers via electrode portions on the base, and (ii) reinforcement portions, which are connected to dummy electrode portions on the base and are more rigid than the branch portions so as to prevent deformation of the branch portions.
