PROBLEM TO BE SOLVED: To firmly join inorganic stocks such as metal by a simple method even if firing is performed at low temperature and under low pressure. SOLUTION: Disclosed is the joining agent for inorganic stocks composed of paste comprising metal colloid particles and a solvent, wherein the metal colloid particles are composed of metal nanoparticles (A) and a dispersant (B), further, the metal nanoparticles (A) have the number average particle diameter of≤50 nm and also have the particle diameter of 100 to 200 nm. The metal nanoparticles (A) are composed of the metal nanoparticles (A1) with the particle diameter less than 100 nm and the metal nanoparticles (A2) with the particle diameter of 100 to 200 nm. Also, the volume ratio of both may satisfy the former/the latter=90/10 to 30/70. The joined body of inorganic stocks obtained by sintering the joining agent for inorganic stocks while interposed between the inorganic stock (C1) and the inorganic stock (C2) is firmly joined.
