Abstract

A particle composition includes metal fine particles composed of a metal element having a bulk melting point of greater than 420° C. with a primary particle diameter of primary particles of the metal fine particles being 1 nm to 500 nm, a part of or an entire surface of the metal fine particles being coated with a coating material; a low melting point metal powder composed of a metal or alloy having a bulk melting point of 420° C. or less; and an activating agent that decomposes and removes the coating material from the surface of the metal fine particles after the low melting point metal powder is melted, wherein a content of the metal fine particles containing the coating material is 0.5 mass % to 50 mass %, and a ratio ([inorganic compound/metal fine particles]×100 (mass %)) of the inorganic compound in the metal fine particles is 0.1 mass % to 50 mass %.
