To form an air electrode containing ZrOby a relatively simple method.SOLUTION: The method of manufacturing an electrochemical reaction single cell including: an electrolyte layer; an air electrode containing ZrO; and a fuel cell electrode facing the air electrode across the electrolyte layer, includes steps of: disposing an air electrode precursor to be an air electrode in a space facing a zirconia-containing member having at least an outer surface made of a material containing ZrO; and performing heat treatment on the air electrode precursor and the zirconia-containing member disposed in the space.SELECTED DRAWING: Figure 6 【課題】比較的に簡単な方法により、ＺｒＯ２を含む空気極を形成する。【解決手段】電解質層と、ＺｒＯ２を含む空気極と、空気極に対して、電解質層を挟んで対向する燃料極と、を備える電気化学反応単セルの製造方法は、空気極となる空気極前駆体を、少なくとも外表面がＺｒＯ２を含む材料により構成されたジルコニア含有部材が面する空間内に配置する工程と、空間内に配置された空気極前駆体とジルコニア含有部材とに熱処理を施す工程と、を含む。【選択図】図６
