The object of the invention is to provide a photothermographic material high in sensitivity and image quality, and excellent in storability in the undeveloped state, which is used for medical images or photomechanical processes. A photothermographic material is described, which comprises a support having provided on one side thereof at least one light-sensitive silver halide, light-insensitive organic silver salt, reducing agent for a silver ion and binder, in which the light-sensitive silver halide has an average grain size of 0.001 mum to 0.06 mum, and the material comprises at least two kinds of organic polyhalogen compounds, at least one of which is an organic polyhalogen compound represented by the following formula (1): wherein Z1 and Z2 each independently represents a halogen atom, X1 represents a hydrogen atom or an electron attractive group, Y1 represents a -CO- group or an -SO2- group, Q represents an arylene group or a divalent heterocyclic group, L represents a connecting group, W1 and W2 each independently represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group, and n represents an integer of 0 or 1.
