Disclosed herein is a gold powder comprises gold particles, and sulfur present on a surface of at least a part of the gold particles. A sulfur amount of the sulfur present on the surface per unit surface area is 220 g/m.sup.2 or more and 1500 g/m.sup.2 or less. The sulfur amount is obtained by dividing a surface sulfur amount per unit mass by specific surface area of the gold particles. The surface sulfur amount is obtained by a quantitatively analysis of a treated liquid obtained by nitric acid extraction of the gold particles.
