PURPOSE:To make the identification easy, by a method wherein a liquid recording head is manufactured using photosensitive resin whose colors are divided by adding dye or pigment of different color according to the difference of the specification of the nozzle of the liquid jet recording head. CONSTITUTION:Ink passage walls are formed on a substrate surface 8 on which liquid discharge energy generating bodies 2 are placed, and in the liquid jet recording heads 10, 11, 12 which are composed by laminating a cover 6 on ink passages 5, photosensitive resin are colored red, blue and yellow by adding dyes. In the colored liquid jet recording heads 13, the heads 10, 11, 12 are designed to discharge yellow liquid, magenta liquid and cyan liquid respectively. Blue colored photosensitive resin is used for the head 10 which discharges yellow liquid, for the head 11 which discharges yellow magenta liquid, and for the head 12 which discharges red cyan liquid. When heads of which shapes are resemble are assembled, the identification by colors is made easy. |
