ABSTRACT:
It is an objective of the present invention to provide a printing element substrate supporting member made of resin material by which, without changing the inclusion rate of filler in the resin material, the linear expansion coefficient can be reduced, the deformation under a heating environment can be suppressed, and the printing element substrate can be suppressed from being peeled or broken. Thus, the printing element substrate supporting member of the present invention is formed by resin material including fibrous filler and has a supporting section for supporting a printing element substrate in which ejecting orifices capable of ejecting ink are arranged. This supporting section is structured so that the filler is oriented along the direction along which the plurality of ejecting orifices are arranged.
