A heat source simulation structure includes a heating body and a heating member to form a simulation heat source main body for conducting heat. The simulation heat source main body is enclosed in an outer case and a heating substrate with electrical insulation and heat insulation properties to avoid dissipation of the heat. The heating member is electrically connected with an external power supply for heating the heating body. A thermocouple member is disposed on the heating body corresponding to the heating member. A temperature monitoring port is connected with a data collection meter for recording the temperature of the heating body. By means of the heat insulation design enclosing the simulation heat source main body, the contact thermal resistance between the heating member and the heating body is reduced, further to lower the heat loss of the heat source simulation structure and enhance the measurement precision and reliability.
