PROBLEM TO BE SOLVED: To provide a device to prevent external metal ions from being captured into a measuring substance. SOLUTION: This diaphragm pressure mediating device has a hollow space formed between a shell 1 and a cap 2, and the hollow space is divided into a pressure-absorbing space 24 for providing fluid having measured pressure, a bleeding space between diaphragms 61, 62, and a pressure transfer space 13 filled with measuring fluid to be pressure transferred to a pressure measuring device 10 by two parallel diaphragms (6:61, 62). The diaphragms (6:61, 62) comprise a perfluoroalkoxy copolymer (PFA), and are formed congruently with profiles under insertion of a synthetic resin fiber core.
