A fuel cell includes: a porous anode; and an electrolyte layer that is provided on the anode and includes solid oxide having oxygen ion conductivity, wherein the anode has a structure in which an anode catalyst is provided in a void, wherein, in a cross section of the anode and the electrolyte layer in a stacking direction thereof, an average void diameter of voids in the anode is 0.1 μm or more and 2 μm or less, wherein, in the cross section, a D10% diameter of void diameter distribution of the voids in the anode is 0.1 μm or mode and 2 μm or less, wherein a D90% diameter of the void diameter distribution is 1 μm or more and 7 μm or less.
