The present invention provides a method for producing a metal structure comprising a substrate and a metal film formed on the substrate; comprising the steps of providing surface having irregularities made of a electrical conductor in the area of the substrate where the metal body or film is to be formed; and preferentially forming the metal body or film by electroplating in the area provided with the conductive surface having irregularities. The plating bath may preferably contain an additive compound such as a cyanine dye which is capable of suppressing the plating reaction, and which loses such plating-suppressing effect with the progress of the plating reaction. The metal film can be produced by electroplating in the area provided with the surface having irregularities.

In an electrode in electrochemical device, particularly an anode lithium ion secondary battery, a cathode for use in alkali storage battery, an electrode for use in fuel cell, or a capacitor electrode, a metal structure has nano size micro-pillars is constructed with an electrode active material being formed on the surface of the metal structure. The metal structure having nano size micro-pillars can be formed, for example, by forming a metal layer as an electrode material by plating to the surface of a substrate having pores and then removing the substrate by dissolution, the metal filled in the pores of the substrate to form a group of micro-pillars. And the active material can be formed by depositing metal by plating. Since the active material is in direct contact with the conductive skeleton, the conducting agent for connecting the active materials to each other may not be added at all.

Provided are an electrode, an electrolysis cell, and an electrochemical analyzer that improve the long-term stability of analysis data. A working electrode, a counter electrode, and reference electrode are disposed in an electrolysis cell. The working electrode is obtained by forming a lead wire in a composite material having platinum or a platinum alloy as a base material, in which a metal oxide is dispersed, or in a laminated material obtained by laminating a valve metal and platinum such that the cross sectional crystal texture in the thickness direction of the platinum is formed in layers and the thickness of each layer of the platinum is 5 micrometers or less. The metal oxide is selected from among zirconium oxide, tantalum oxide, and niobium oxide, and the metal oxide content of the platinum or the platinum alloy is 0.005 to 1 wt % in terms of the zirconium, tantalum, or niobium metal.

Provided is high corrosion resistant equipment for a plant having the lining structure which exhibits high reliability against breaking of a joining portion over a long use period. The high corrosion resistant equipment for a plant includes a lining plate and a support portion which are made of a high corrosion resistance material and a structural material portion made of a steel material or the like. The lining plate and the support portion include a joining portion to which friction stirring is applied. The support portion is assembled into or fastened to the structural material portion by means of the geometrical structure with a gap interposed between the support portion and the structural material portion. Due to such a constitution, high corrosion resistant equipment for a plant having the lining which exhibits high reliability can be acquired.
