A calorific value measuring system having a container filled with a mixed gas to be measured; a microchip includes a heating element producing heat at a plurality of heat producing temperatures, disposed within the container; a measuring portion measuring a value of an electric signal from the heating element contacting the mixed gas being measured, at each of the plurality of heat producing temperatures; an equation storage device storing a calorific value calculating equation that has, for independent variables, the electric signals from the heating element at the plurality of heat producing temperatures and, as the dependent variable, the calorific value; and a calorific value calculating portion calculating the value of the calorific value of the mixed gas being measured by substituting the measured values for the electric signal from the heating element into the independent variables in the calorific value calculating equation.
