Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pressure-measuring instrument that has a simple constitution and enhanced safety. SOLUTION: This pressure-measuring instrument 10 is constituted by mounting, for example, a metallic pole (columnar pipe section) 13 on a support section 12 set up on a concrete-made support base 11. A protective case 14 for housing a pressure sensor, etc., is supported by the pole 13, in a state where the case 14 is fixed to the pole 13 at an appropriate height. A gas is introduced from a pipe 16, buried underground to the pressure sensor housed in the protective case 14 through a connecting pipe 17. The inside of the pole 13 is formed in a hollow section, and the ground portion 17B and valve 17A of the pipe 17 are housed in the hollow section. The protective case 14 has a pressure- measuring chamber housing the pressure sensor and a control chamber housing the electric equipment, etc., of a control section and the chambers are separated from each other.
