摘要： PROBLEM TO BE SOLVED: To obtain an evaluation method which can measure a delicate difference in the pressure loss of a honeycomb structure whose pressure loss is very small. SOLUTION: By determining the target gas flow rate and allowable range of the gas flow rate and supplying the gas to a honeycomb structure, supplying gas to the honeycomb structure with a determined allowable range to the flow rate of the gas, the differential pressure between the inflow and outflow sides of the honeycomb structure is measured, when the gas flow rate is within the allowable range. The pressure loss of the honeycomb structure at the target gas flow is obtained as the differential pressure obtained by converting to the target flow rate, by using the measured differential pressure and the measured gas flow rate.
