Abstract:
1. An attachment quantity measurement device comprising: an electromagnetic wave output device that outputs an electromagnetic wave to be measured having a frequency equal to or higher than 0.01 THz and equal to or lower than 100 THz toward a carrier, including an attachment hole to which a catalyst is attached and a non-attachment hole to which the catalyst is not attached; an electromagnetic wave detector that detects the electromagnetic wave to be measured which has transmitted through the carrier; a reference value obtainer configured to obtain a reference value, based on the electromagnetic wave detected by the electromagnetic wave detector, the reference value being one of an absorption rate, a group delay, and a dispersion of the electromagnetic wave to be measured in the non-attachment hole; and an attachment quantity obtainer configured to obtain, based on the electromagnetic wave detected by the electromagnetic wave detector and the reference value obtained by the reference value obtainer, at least one of a weight and a density of the catalyst present in the attachment hole.
