Summary: | PROBLEM TO BE SOLVED: To provide a pattern forming method ensuring precise pattern dimensions.SOLUTION: The pattern forming method includes the steps of: forming a processed layer over a substrate; preparing a noble metal microparticle layer coating liquid, which contains microparticles coated by high polymer material, by adding a second fluid dispersion a high polymer material which containing polymer chain having a base metal at the end thereof and a second solvent to a first fluid dispersion which contains noble metal microparticles and a first solvent; arranging noble metal microparticles coated by high polymer material over the processed layer by using the noble metal microparticle layer coating liquid; and transferring a rugged pattern of noble metal microparticles coated by the high polymer material.
