A liquid discharging head comprises a discharge opening for discharging a liquid, a bubble generation region for generating a bubble in a liquid, and a movable member disposed so as to face the bubble generation region and arranged as displaceable between a first position and a second position more distant from the bubble generation region than the first position, wherein the movable member has the narrowest space in the bubble generation region and is displaced from the first position to the second position by pressure based on generation of the bubble in the bubble generation region, and wherein the bubble is made to expand greater downstream than upstream with respect to a direction toward the discharge opening, by displacement of the movable member.

A liquid discharging head comprising:
A fabrication process of a liquid discharging head comprising a first recess portion for forming a first liquid flow path in fluid communication with a discharge opening, a movable member arranged as displaceable relative to the first recess portion, a second recess portion for forming a second liquid flow path for displacing the movable member, and discharge energy generating means disposed corresponding to the second recess portion,
A fabrication process of a liquid discharging head comprising a first recess portion for forming a first liquid flow path in fluid communication with a discharge opening, a partition wall having a movable member arranged as displaceable relative to the first recess portion, a second recess portion for forming a second liquid flow path for reserving a liquid for displacing the movable member of the partition wall, and discharge energy generating means disposed corresponding to the second recess portion, the fabrication process comprising the steps of forming walls for forming the second recess portion on an element substrate having the discharge energy generating means and thereafter successively joining members respectively comprising the movable member and the first recess portion with the second recess portion so that at least a space between the partition wall and the discharge energy generating means becomes narrowest by providing the partition wall with a bent portion or a slant portion so as to provide a narrower space in the bubble generation region than in a region upstream thereof.
