PURPOSE: To form an ink passage, for example, a fine nozzle or the like.
CONSTITUTION: A composition of a resin which is set by an active energy ray working as an adhesive is prepared. A solution of the composition is applied onto a first base material 10 by a spinner, dried on a hot plate, thereby to obtain an active energy ray setting resin layer 11 of 10μm thickness. Ultraviolet rays are cast from above the first base material 10 via a mask with a shielding part corresponding to a groove as an ink passage. Then, the unnecessary part of the resin layer 11 is selectively dissolved and removed, so that a resin layer 11a is formed. Further, the base material 10 is heated so as to add adhesive properties and flexibility to the resin layer 11a. A second base material 12 is registered and thermally pressed onto the resin layer 11a. Thereafter, the resin layer 11a is completely set by heating for 30 minutes at 150°C and the first and second base materials 10, 12 are perfectly bonded.
