1. A reducing gas detection material comprising:
a palladium oxide;
a metallic palladium; and
a carbon compound,
the reducing gas detection material having reactivity with a reducing gas,
wherein when a number of palladium atoms contained in the palladium oxide is represented by PO and a number of palladium atoms contained in the metallic palladium is represented by PM, a ratio RP of the number of palladium atoms contained in the metallic palladium with respect to a total of the number of palladium atoms contained in the palladium oxide and in the metallic palladium, as represented by expression RP=PM/(PM+PO), is 0.17 to 0.45.
