Abstract
Provided is a highly reliable fuel cell that improves power generation efficiency of the fuel cell and that is less likely to cause damage to an electrode and an electrolyte film. The fuel cell includes a support substrate () having a region in which a support portion having a mesh-like shape in a plan view is provided, a first electrode 4 on the support substrate, an electrolyte filmon the first electrode, and a second electrodeon the electrolyte film. The first electrode includes a first thin film electrodeA formed in a manner of covering at least the region, and a first mesh-like electrodeB connected to the first thin film electrode and provided corresponding to the support portion. The first mesh-like electrodeB has a film thickness larger than that of the first thin film electrode and has a mesh-like shape in a plan view.
