PROBLEM TO BE SOLVED: To provide a noncontact type viscometer capable of reliably measuring the viscosity of a liquid to be measured without any contact with it. SOLUTION: The noncontact type viscometer 1 for measuring the viscosity of a liquid to be measured housed in a prescribed container is provided with both a low-frequency supply means 33 for supplying low-frequency acoustic waves of a prescribed frequency for the liquid to be measured 4 housed in the prescribe container 2 and a laser displacement means 5 for irradiating the liquid to be measured 4 housed in the container 2 with a laser beam, receiving a reflected laser beam from the liquid to be measured 4, and determining displacements on the basis of information on the irradiating laser beam and the reflected laser beam. On the basis of the displacements from the laser displacement means 5, it is possible to acquire the viscosity of the liquid to be measured 4. COPYRIGHT: (C)2008,JPO&INPIT
