PROBLEM TO BE SOLVED: To provide a static measuring device for liquid capable of equivalent measuring for the deterioration of a liquid-containing electric apparatus. SOLUTION: In such a static measuring device that a static evaluation of a liquid-containing electric apparatus, equipped with a static-electricity generating part for generating static electricity in a fluid and in which fluidized insulating liquid is enclosed in a vessel, is obtained by using a filter 4, comprising the same material as a solid insulator used in the liquid-containing electric apparatus, as a static-electricity generating part, the surface part of the filter 4 of the static-electricity generating part is formed so as to have equality with the deterioration state of the surface part of the solid insulator of the liquid- containing electric apparatus.
