A microbial fuel cell (1) comprises: a negative electrode (10) which is formed from a carbon material (11) obtained by laminating a plurality of graphenes (12), and in which the area of the surface exposed along the graphene layering direction (X) of the carbon material is 1.0 x 10-5 to 20 cm2/cm3 in terms of the carbon material volume; and a positive electrode (20) opposing the negative electrode. The negative electrode and positive electrode are immersed in an electrolyte (70) and at least a portion of the positive electrode is exposed to a gas phase (2). 微生物燃料电池(1)具有负极(10)、和与负极相对置的正极(20)，其中，负极(10)由层叠有多层石墨烯(12)的碳材料(11)构成，碳材料的沿石墨烯层叠方向(X)的露出表面的面积相对于碳材料的体积为1.0×10～20cm/cm；而且负极和正极浸渍于电解液(70)中，正极的至少部分在气相(2)中露出。
