PROBLEM TO BE SOLVED: To provide a joining agent for inorganic stocks, which has excellent dispersibility and storage stability at room temperature, and can firmly join inorganic stocks such as metal even when being fired at low temperature under low pressure. SOLUTION: In the joining agent for inorganic stocks composed of metal colloidal particles and paste including the dispersion medium of the metal colloidal particles, the metal colloidal particles are composed of metal nanoparticles (A) and protective colloid (B) for dispersing the metal nanoparticles (A), and also, the protective colloid (B) is composed of an organic compound (B1) having a carboxyl group and a polymer dispersant (B2). The joined body of inorganic stocks obtained by sintering the joining agent for inorganic stocks while the joining agent for inorganic stocks is interposed between an inorganic stock (C1) and an inorganic stock (C2)is firmly joined.
