PROBLEM TO BE SOLVED: To protect the electrodes of an electrode switch to be a liq. level detector from treating liqs. in a liq. level detector of a photosensitive material processor for treating developing papers. SOLUTION: The level detector uses a machined coaxial cable 232 as an electrode 230 for detecting the liq. level, and the electrode 230 is constituted by exposing a first and second electrodes 234, 236 on the coaxial cable 232 and coating the entire coaxial cable 232 with a conductive resin 238, including the first and second electrodes 234, 236, thereby protecting the first and second electrodes 234, 236 from treating liqs. owing to the conductive resin 238.
