PURPOSE:To produce an ornamental electrode with which a sufficient electrode area is assured and which has an excellent adhesive property to a functional film and a long life by forming the functional film to the area of >=2 times the area of a metallic layer. CONSTITUTION:Sapphire is used as a substrate 3 of, for example, a metallic electrode 1 and gold is used as a metal. The gold is produced by an IC producing process (pattern formation by a resist, vacuum vapor deposition, sputtering), etc. Bovine serum albumin crosslinked with glutaraldehyde is used as the functional film 2 and is applied by spin coating. The width of the functional film 2 is specified to 100mum and the thickness to 2mum. The metallic electrode is formed to 50mum width and 1mum thickness. The sufficient part where the substrate 3 and the functional film 2 adhere is taken and the peeling of the film 2 is prevented by forming the film 2 to the area of >=2 times the area of the metallic layer in such a manner. The long-life ornamental electrode with which the sufficient electrode area is assured and which has the excellent adhesive property to the functional film is produced in this way. |
