A thin membrane for measuring protease activity, which is formed on a support and, which comprises one or more kinds of substances selected from the group consisting of a transferrin derivative and an albumin derivative and is crosslinked and/or substantially water-insoluble. The membrane enables selective measurement of protease activity of a particular class of protease such as matrix metalloproteinase 7.
