PURPOSE: To obtain a membrane for chemical analysis, and a production method thereof, in which cross contamination due to a sample or a reagent can be prevented between the using parts. CONSTITUTION: A part 3 impregnated with wax is provided around a part 2 where a membrane 1 for chemical analysis, e.g. a nitrocellulose membrane, is used. The membrane 1 for chemical analysis is produced by immersing a filter paper having holes of same shape as the hole at the using part 2 into a molten wax, superposing the filter paper on a film for producing the chemical analytic film, and then pressing them to impregnate the film for producing the chemical analytic film with wax. |
