EXAMPLE - Surfactant comprising a phosphoric acid mono-(2-(2-(2-(4-nonyl-phenoxy)-ethoxy)-ethoxy)-ethyl) ester compound of formula (I) (1 g) was dispersed in a solvent (40 g) prepared by mixing butyl carbitol (BC)/butyl carbitol acetate (BCA) (weight ratio of 7:3). Phosphoric acid aqueous solution (10 g, 85%) was added to the mixture. The resulting mixture was dispersed to prepare a mixture having reverse micelle structure including a functional phosphoric acid. Ethylcellulose binder (30 g) was added to a solvent (70 g) prepared by mixing BC/BCA to given an organic vehicle. The mixture (1.5 g) including a reverse micelle structure was mixed with the organic vehicle (6.5 g), and silver powder (40 g), copper-based metallic glass (1 g), diethyl phthalate (1 g), and glycolic acid ethoxylate 4-nonylphenyl ether (0.7 g) were added to it. The resulting mixture was uniformly mixed in a 3-roll milling method to give a paste.    n = 1-20.
