To provide a tube-type fuel cell, which has an electricity-collecting structure that makes it possible to collect electricity in axially-orthogonal directions in an outside electricity collector of single cell constituting the tube-type fuel cell, and whose electricity-collecting distance is so less as to make it possible to be of low resistance. A tube-type fuel cell according to the present invention is such that, in a tube-type fuel cell comprising: a tube-shaped single cell 1 being completed by putting an inside electricity collector 11, a first catalytic electrode layer 12, an electrolytic membrane 13, a second catalytic electrode layer 14 and an outside electricity collector 15 in a lamination in this order from an axially-orthogonal inner side; and a battery case 2 for bundling a plurality of the single cells 1 together and then accommodating the single cells therein; a plurality of the single cells 1 being accommodated together within the battery case 2 while contacting with each other electrically by way of at least a part of outer peripheral surfaces 151 of the outside electricity collectors 15 of the single cells 1, thereby collecting electricity in axially-orthogonal directions thereof.
