NOVELTY - An electroconductive component (1) has a base material (10) and an electroconductive layer (20) provided on the base material. The electroconductive layer contains a binder which is a sol-gel cured product having a three-dimensional cross-linking structure including a partial structure (I) and is obtained by hydrolyzing and polycondensing at least one alkoxide compound of an element chosen from silicon, titanium, zirconium and aluminum, and metal nanowires having a mean minor axis length of 150 nm or less. The mass ratio of alkoxide compound to metal nanowires is 0.25/1-30/1.    USE - Electroconductive component is used for touch panel and solar cell (all claimed) e.g. CGIS solar cell.    ADVANTAGE - The electroconductive component has excellent electroconductivity and contact resistance. The touch panel and solar cell using the electroconductive component have excellent etching properties.    DETAILED DESCRIPTION - An electroconductive component has a base material and an electroconductive layer provided on the base material. The electroconductive layer contains a binder which is a sol-gel cured product having a three-dimensional cross-linking structure including a partial structure of formula: -M1-O-M1- (I) and is obtained by hydrolyzing and polycondensing at least one alkoxide compound of an element chosen from silicon, titanium, zirconium and aluminum, and metal nanowires having a mean minor axis length of 150 nm or less. The mass ratio of alkoxide compound to metal nanowires is 0.25/1-30/1. The surface roughness (Ra) of surface on side opposite to the surface of the base material is 0.5-50 nm.    M1=Si, Ti, Zr or Al.    An INDEPENDENT CLAIM is included for manufacture of electroconductive component, which involves applying liquid composition containing partial condensate obtained by hydrolyzing and polycondensing at least one alkoxide compound of element chosen from silicon, titanium, zirconium and aluminum, and metal nanowires, on a base material, forming a liquid film on the base material, and forming sol-gel hardened material by hydrolyzing and polycondensing the partial condensate in the liquid film.
