PROBLEM TO BE SOLVED: To provide a highly accurate salinity measuring device for a structure surface for easily performing extraction and measurement of salinity sticking to a structure, causing no remaining of air in a liquid holding chamber even if a detecting object surface is horizontal or at any angle, and causing no measurement error. SOLUTION: This salinity measuring device is composed of a device body 10 having an operation panel 10a and a display part 10b together with an arithmetic processing unit, and a detecting part 11 connected to the device body 10. The detecting part 11 has the liquid holding chamber 13 having an opening 12 on one end, a liquid supply passage 14 for supplying pure water for extracting the salinity, a plurality of air bleeding passages 16a and 16b, an agitator 17 for agitating liquid, and a sensor 18 for measuring the salinity. An upper bottom surface 13a of the liquid holding chamber 13 is formed as an inverse conical taper surface. COPYRIGHT: (C)2004,JPO
