Abstract: A multilayer electronic component includes a body including a dielectric layer and an internal electrode alternately disposed with the dielectric layer, and an external electrode disposed on the body. The dielectric layer includes a BaTiO3-based base material main ingredient, a sub-ingredient including Dy, and an additive. The additive is one or more of Sm, Gd and Tb, and a content of the additive is 25 mol or more and less than 50 mol relative to 100 mol of Dy. The dielectric layer includes a plurality of dielectric grains. When an average grain size of the plurality of dielectric grains is represented by G, and an average thickness of the dielectric layer is represented by td, 1.75≤td/G≤2.23 is satisfied.
