Abstract
A charge amount measurement method includes applying a periodically-changing voltage between a pair of electrodes arranged with a sample interposed therebetween in a cell in which the sample is encapsulated, the sample being created by mixing a material to be measured with a nonpolar liquid crystal whose liquid crystal molecules do not rotate due to an application of the periodically-changing voltage; and measuring an amount of charge in the material to be measured, based on a current that flows through the pair of the electrodes and the sample due to the application of the periodically-changing voltage.
