Abstract
A positive electrode for an air battery and an air battery using the positive electrode are provided, that make it possible to inhibit an electrolyte solution decrease in the battery and prevent the problems associated with the electrolyte solution decrease without causing an increase in manufacturing costs. A positive electrode for an air battery includes an expanded graphite sheet. It is desirable that the expanded graphite sheet contain expanded graphite in an amount of 80 mass % or greater. It is desirable that the expanded graphite have a bulk density of from 0.2 Mg/mto 2.0 Mg/m. It is desirable that the expanded graphite sheet have a thickness of from 0.1 mm to 3.0 mm.
