A light jet recording head has a liquid passage communicated to the discharging outlet of the liquid provided on a substrate surface, said passage being formed by subjecting a layer of a resin composition curable with an active energy ray to a predetermined pattern exposure with the use of said active energy ray to thereby form a cured region of said resin composition and removing the uncured region from said layer, said resin composition comprising: (i) a linear polymer having a glass transition temperature of 50.degree. C. or higher and a weight-average molecular weight of about 3.0.times.10.sup.4 or more; and (ii) an epoxy resin comprising at least one compound having two or more epoxy groups in the molecule, the epoxy groups existing in said epoxy resin being partially esterified with an unsaturated carboxylic acid.
