PROBLEM TO BE SOLVED: To supply, using a simple structure, fluid pressure equipment with pressure fluid controlled to low pressure. SOLUTION: The fluid pressure controller includes a first diaphragm 50a which is bent under the action of secondary pressure fluid (output pressure) introduced into a pressure chamber 60; a second diaphragm 50b which is bent under the action of pilot pressure supplied into a pilot chamber 68; and a supply valve element 28a which is displaced under the bending action of the first and second diaphragms 50a and 50b via a rod member 38. The pressure-receiving area of the second diaphragm 50b acted upon by the pilot pressure is set to be smaller than the pressure-receiving area of the first diaphragm 50a acted upon by the output pressure.
