PURPOSE: To reduce a partitioning wall forming cost to fine the partitioning wall width, by constituting a partitioning wall layer, formed on a glass base board, of the sintered body of a thin plate state glass fine particle. CONSTITUTION: The partitioning wall 2 of a fine particle, composed of thin plate state glass having a thickness of 2μm or thinner, is formed on a glass base board 1. Coating liquid, prepared by blending photosensitive resin and an organic solvent, is applied to a thin plate state glass fine particle to be dried. Ultraviolet light 6 is irradiated to the glass base board 1 via a photomask 5 to make the photosensitive resin be sensitized. A resultant is developed to remove an unnecessary part to be baked and sintered, thereby obtaining a partitioning wall forming glass plate. When a thin plate state glass fine particle is used as a glass fine particle in the coating liquid, since the glass fine particle is arranged in a direction parallel to the base board 1 at the time of coating, the ultraviolet light becomes difficult to be expanded in a direction other than an irradiation part in an exposure process, and the attenuation of the ultraviolet light is reduced in a thickness direction, thereby a fine partitioning wall, having high height and narrow width, can be formed. |
