Abstract:
1. A method of manufacturing a liquid discharge head including a discharge port to discharge liquid and a flow path forming member, for forming a flow path communicated with the discharge port, said method comprising, in order, the steps of: (a) forming a photosensitive material layer for forming the flow path forming member on a first substrate having a liquid discharge energy generating element which generates energy for discharging the liquid from the discharge port; (b) performing pattern exposure on the photosensitive material layer to form a latent image portion of a flow path pattern in the photosensitive material layer; (c) laminating a second substrate which is substantially parallel to the photosensitive material layer constituted of an inorganic material on the photosensitive material layer in which the latent image has been formed; (d) forming the discharge port in the second substrate; and (e) removing the latent image portion from the photosensitive material layer to form the flow path.
