An object of the present invention is to provide a method for producing a gold porous body having pores having a pore diameter of 50 to 1000 nm, and the gold porous body. A method for producing a gold porous body according to the present invention includes, for example, a step of immersing a molybdenum plate in chloroauric hydrochloric acid for 1 hour to precipitate gold nanoparticles (“coating step”), and 930 ° C. in an argon atmosphere. Heating the molybdenum plate for 10 minutes to join the gold nanoparticles (“sintering step”), and heating the molybdenum plate to about 900 ° C. in an oxidizing atmosphere to oxidize and sublimate the molybdenum plate. Step ("sublimation step"). By the above production method, for example, a membranous gold porous body having pores with a pore diameter of 100 to 300 nm, a porosity of 14.5%, and a thickness of 500 nm can be produced.
