A colloidal solution of fine metal particles, wherein metal particles having an average particle diameter of less than 10 nm are united or aggregated into particles having an average particle diameter of 10 nm or more and dispersed; a colloidal solution of fine metal particles, wherein a black colloidal solution of fine metal particles has been heat-treated so as to develop a color; a colloidal solution of fine metal particles, which has alloy particles formed by the heat treatment of a mixed colloidal solution having fine particles of two or more different metal; and a metal colloid pigment, an electroconductive paste or electroconductive ink, which comprises the above colloidal solution of fine metal particles as a part thereof or is prepared by the above colloidal solution of fine metal particles. Une solution colloïdale de fines particules métalliques, dans laquelle les particules métalliques ayant un diamètre moyen de moins de 10 nm sont réunies ou agrégées en particules ayant un diamètre moyen de 10 nm ou plus et dispersées ; une solution colloïdale de fines particules métalliques, dans laquelle une solution colloïdale noire de fines particules métalliques a été traitée à la chaleur pour la colorer ; une solution colloïdale de fines particules métalliques, ayant des particules d'alliage formées par traitement à la chaleur d'une solution colloïdale en mélange ayant de fines particules de deux ou plusieurs métaux différents ; et un pigment métallique colloïdal, une pâte électroconductrice ou une encre électroconductrice qui comprend la solution colloïdale de fines particules métalliques citée ci-dessus ou est préparé à partir de la solution de fines particules métalliques.
