Abstract: Provided is an ink for use in electronic component production making use of screen printing, which is suitable for actually allowing fine lines with high precision to be drawn in screen printing, and for actually allowing successive screen printing operations to be performed. The ink for screen printing of the present invention includes surface-modified silver nanoparticles (A) and a solvent (B), and has a viscosity at a shear rate of 10 (1/s) and 25° C. of 60 Pa·s or more. The surface-modified silver nanoparticles (A) each include a silver nanoparticle and an amine-containing protective agent coating the silver nanoparticle. The solvent (B) includes at least a terpene solvent. In solvent (B), a content of solvents having a boiling point of less than 130° C. is 20 wt % or less based on the total amount of solvents.
