METHOD AND APPARATUS FOR FORMING THIN FILM, AND LIQUID DROPLET DISCHARGING HEAD

摘要

PROBLEM TO BE SOLVED: To solve such a problem that a uniform coating film can not be formed efficiently on a member to be coated owing to a difference in level caused by a transfer mark remaining after a coating agent is transferred to the member to be coated. SOLUTION: The subject apparatus for forming a thin film is provided with: an anilox roll 51 being a holding member having a uniform minute concave part on the surface for storing an adhesive 16 to be supplied; a doctor blade 53 for removing the excessive adhesive 16 stuck to parts other than the concave part of the anilox roll 51; and a letterpress roll 55 having on the outer peripheral surface a letterpress 54 to the surface of which the adhesive 16 stored in the concave part of the anilox roll 51 is transferred by contacting with the surface of the anilox roll 51 so that the adhesive 16 transferred to the surface is transferred to the member 12 to be coated. A step to transfer the adhesive 16 on the letterpress 54 of the letterpress roll 55 to the member which is to be coated and is sent by a stage 57 by contacting with the surface of a flow passage plate 12 being the member to be coated and transfer the adhesive 16 to the letterpress 54 from the anilox roll 51 is repeated two or more times.
