PROBLEM TO BE SOLVED: To nondestructively precisely control curing progression degree of an epoxy resin of a large molecular weight by a method wherein a measuring range of equivalent resistivity of a resin capable of being detected with a dielectric measuring sensor is enlarged. SOLUTION: A dielectric measuring sensor 10A for measuring equivalent resistivity of a resin in a casting mold 6 is set to the casting mold 6, and a sensor-heating heater 17 is fitted to the dielectric measuring sensor 10A. In a curing monitor process, the sensor-heating heater 17 raises temporarily temperature of the resin in the casting mold 6, and the equivalent resistivity is lowered thereby to within a measuring sensitivity range of the dielectric measuring sensor 10. Then, the equivalent resistivity of the resin in the casting mold 6 is measured with the dielectric measuring sensor 10. |
