Abstract: The purpose of the present invention is to provide a dental-pulp-cavity model which is capable of forming a simulated dental-pulp cavity having a desired shape, and which can be produced easily. This dental-pulp-cavity model (1) is provided with: a tooth body section (10) configured from a transparent member; and a simulated dental-pulp cavity (30) formed in the tooth body section (10). The tooth body section (10) is provided with: a first main body member (11) provided with a first contact surface (12); a second main body member (21) provided with a second contact surface (22) which comes into contact with the first contact surface (12); and dental-pulp-cavity grooves (13, 23) which are formed in the first contact surface (12) and/or the second contact surface (22), and which correspond to the shape of the simulated dental-pulp cavity (30).
