Abstract
A process for producing a liquid jet recording head comprises the step of laminating a solid layer for formation of a liquid channel, a photosensitive material to be provided so as to cover over the solid layer, a discharge opening plate provided with a discharge opening communicated to the liquid channel in this order on a substrate; the step of irradiating an active energy ray in a pattern on the photosensitive material layer; and the step of removing the solid layer and the uncured portion of said photosensitive material layer corresponding to the pattern to form the liquid channel.

A process for producing a liquid jet recording head, said process comprising the steps of:
- filling a filling material having photosensitivity to active energy, in concave portions of a convex-concave member, the convex-concave member having convex and concave protions on a same surface of the member and the filling material being provided for forming a liquid channel on the member communicating with a discharge opening for discharging liquid;
- providing a substrate having a sheilding layer for shielding against the active energy, over the filling material, the shielding layer being provided on the side of the substrate opposing the convex-concave member;
- irradiating the active energy in a pattern on the filling material by use of the shielding layer;
- and
- removing the convex portions of the convex-concave member and a part of the filling material corresponding to the pattern to form the liquid channel.
