Viscosity of an ionic liquid (1-methyl-3propyl imidazolinium iodide) in ethylisopropylsulfone is measured using the shear horizontal (SH) wave method in which viscosity is determined by a delay in phase propagation of the SH wave. The sample is filled into a cell structure on a SH wave device. In the cell structure, there are two indium-tin oxide electrodes on the surfaces of the cell which allow us to measure the electroviscous effect of the ionic liquid. The results of electroviscous measurements show phase shift depending on voltage. The increase of a voltage decreases the phase of the SH wave, and then the phase recovers in the absence of the applied voltage. Further we found the phase shift depends on the cell thickness. These indicate that the viscosity of the sample increases with increasing electric field
