Abstract: The present invention provides a film-shaped firing composition with excellent printability, a method of producing a film-shaped firing material obtained by using the firing material composition, and a method of producing a film-shaped firing material with a support sheet. A paste-like firing material composition is provided, including sinterable metal particles (10), a binder component (20), and a solvent having a relative evaporation rate of 4.0 or less with respect to butyl acetate, in which a content of the solvent is in a range of 12% to 50% by mass with respect to a total mass of the firing material composition.
