An aqueous ink for ink jet including a resin particle. The resin particle includes a first layer and a second layer in this order from the inside to the outside thereof. The first layer is composed of a first resin, wherein the proportion of a unit derived from an aromatic-group-containing ethylenically unsaturated monomer in the first resin is 10% by mass or less. The second layer has a tetrahydrofuran-insoluble fraction of 10% by mass or more and is composed of a second resin having a unit derived from an aromatic-group-containing ethylenically unsaturated monomer and a unit derived from an ionic-group-containing ethylenically unsaturated monomer, wherein the proportion of the unit derived from the ionic-group-containing ethylenically unsaturated monomer in the second resin is 3% by mass or more to 70% by mass or less.
