To provide manufacturing method and manufacturing installation of electrolyte membrane/electrode structure capable of easily obtaining an electrolyte membrane/electrode structure where positional deviation of the first electrode and solid polymer electrolyte membrane and second electrode, and deformation of the solid polymer electrolyte membrane are suppressed.SOLUTION: A manufacturing method of MEA10 has a first bonding step of bonding an anode electrode 14 to one face 12a of a solid polymer electrolyte membrane 12 to produce a conjugate 60, and a second bonding step of bonding a cathode electrode 16 to the other face 12b. In the first bonding step, the solid polymer electrolyte membrane 12 is sucked and heated via the anode electrode 14 placed on the suction heating surface 26a of a suction heating plate 26. In the second bonding step, the laminate 10a of the conjugate 60 and the cathode electrode 16 is heated while compressing in the lamination direction between the suction heating surface 26a and a heating plate 30.SELECTED DRAWING: Figure 9 【課題】第１電極と固体高分子電解質膜と第２電極との位置ずれや、固体高分子電解質膜の変形が抑制された電解質膜・電極構造体を容易に得ることが可能な電解質膜・電極構造体の製造方法及び製造装置を提供する。【解決手段】ＭＥＡ１０の製造方法は、固体高分子電解質膜１２の一方の面１２ａにアノード電極１４を接合して接合体６０とする第１接合工程と、他方の面１２ｂにカソード電極１６を接合する第２接合工程とを有する。第１接合工程では、吸引加熱板２６の吸引加熱面２６ａに配置したアノード電極１４を介して固体高分子電解質膜１２を吸引及び加熱する。第２接合工程では、接合体６０とカソード電極１６の積層体１０ａを、吸引加熱面２６ａと加熱板３０との間で積層方向に加圧しつつ加熱する。【選択図】図９
