Abstract
A method for producing an actinic ray-sensitive or radiation-sensitive resin composition, the method including passing a solution including an acid compound having a pKa of 2.0 or more through a column packed with an ion-exchange resin, producing an onium salt by using the acid compound having been passed through the column, and mixing together the onium salt and a resin that undergoes an increase in polarity due to action of acid.
