The present invention provides a curable resin composition which is capable of obtaining a cured product having high insulation reliability and flame resistance which are both ion migration resistant and the like, and a dry film having a resin layer obtained from the composition, The composition or the cured product of the dry film, and a printed wiring board having the cured product. The curable resin composition of the present invention is characterized in that it contains a carboxyl group-containing resin, a thermosetting component, a flame retardant, and a curable resin composition of an ion scavenger, and the ion trapping agent is a hydrotalcite-based ion scavenger and hydrotalcite. A mixture of ion trapping agents other than the system. |
