To provide an electro-optical apparatus suitably usable as a reflective display apparatus with excellent visibility. A first substrate having a first electrode on one surface side, a second substrate having a second electrode on one surface side and arranged opposing the first substrate, an electrolyte layer having material used for electrolytic deposition and disposed between the first electrode and the second electrode are included. Each of the first electrode and the second electrode has a concave-convex configuration on one surface side that is in contact with the electrolyte layer. Surface roughness Ra of one side of the first electrode is 0.4 μm or more, and surface roughness Ra of one surface side of the second electrode is 0.02 μm or more and relatively smaller than the surface roughness of the first electrode.
