Original Abstract Submitted

A liquid ejection apparatus includes a nozzle, a pressure chamber, a piezoelectric element, a count processing portion, and a detection processing portion. The nozzle ejects a liquid. The pressure chamber communicates with the nozzle and contains the liquid. The piezoelectric element changes a pressure in the pressure chamber in response to an input of a drive signal. The count processing portion counts a number of times that an electric signal output from the piezoelectric element and corresponding to vibration generated in the pressure chamber in response to the input of the drive signal to the piezoelectric element exceeds a predetermined threshold value. The detection processing portion detects a viscosity of the liquid contained in the pressure chamber, based on a count result of the count processing portion.
