<P>PROBLEM TO BE SOLVED: To provide a detection plate which contributes, when arranged in a detection apparatus for detecting an oil content and a surface active agent, to a compact, inexpensive and portable configuration of the detection apparatus, and is capable of quickly detecting the oil content and the surface active agent in water at high sensitivity, and to provide a detection apparatus including the detection plate, and a detection method using the detection apparatus. <P>SOLUTION: In a detection plate, a detection electric field formation layer forming an electric field for detecting at least either one of an oil content and a surface active agent as a specimen, and a capture layer for capturing the specimen from water including the specimen are arranged in this order. On the capture layer, a capturing recess for capturing the specimen is formed on a face brought into contact with water; water repelling treatment is applied to the face brought into contact with water; and when water is dropped to the face forming the capturing recess under the atmospheric pressure, water does not infiltrate into and fill the capturing recess. <P>COPYRIGHT: (C)2013,JPO&INPIT |
