Abstract

A current density measuring apparatus (100) includes an underwater electric field sensor (1) including a pair of electrode portions (10) and a potential difference (V) measuring unit configured to measure a potential difference (V) between the pair of electrode portions (10) without contacting a test object (80) placed in water, a conductivity meter (2) configured to measure a conductivity (σ) in the water, and a controller (3) configured or programmed to acquire a current density (J) of a current (70, 71) flowing from the test object (80) into the water using the potential difference (V) measured by the underwater electric field sensor (1) and the conductivity (σ) measured by the conductivity meter (2).
