Abstract
A liquid viscosity measurement device for measuring a viscosity of a liquid includes: a substrate; a channel configured to be installed on the substrate so that the liquid flows through the channel; a heating element configured to generate a bubble in the liquid inside the channel; a sensor configured to be placed in a vicinity of the heating element so as to measure a temperature; and a deriving unit configured to derive the viscosity of the liquid by specifying a bubble disappearance time period from generation to disappearance of the bubble based on a change in temperature obtained by use of the sensor, so that the viscosity of the liquid is derived based on the bubble disappearance time period.
