Provided is a conductive ink with which the stopping of ink printing is favorable and which can also suppress deformation such as crushing when surface pressure is applied. The present invention is a conductive ink that forms ribs 22 on a base material 21 by being printed, by screen printing, onto the base material 21 of a separator 11 that constitutes a cell 13 of a fuel-cell stack, wherein the distortion of the ink, the loss tangent of which is 1, is 10 to 100% when the viscoelasticity is measured using a rotary rheometer. |
