The present disclosure provides a conductive ink or a conductive paste having highly conductive property and excellent low-temperature sinterability. One aspect of the present disclosure relates to a conductive ink or a conductive paste containing metal nanoparticles, a water or a hydrophilic solvent having a vapor pressure of 10 hPa or more, and an additive solvent. A distance Ra between a Hansen solubility parameter of the metal nanoparticles and a Hansen solubility parameter of the additive solvent is in a range of from 2.5 to 13. A distance Rb between a Hansen solubility parameter of the water or the hydrophilic solvent and the Hansen solubility parameter of the additive solvent is 35 or less. Another aspect of the present disclosure relates to a method for producing the conductive ink or the conductive paste, and a method for selecting the additive solvent contained in the conductive ink or the conductive paste.
