1. A multilayer electronic component comprising:
a body including a plurality of dielectric layers and internal electrodes disposed to face each other with each of the plurality of dielectric layers interposed therebetween; and
external electrodes connected to the internal electrodes and disposed on outer surfaces of the body,
wherein each of the plurality of dielectric layers includes a BaTiO3-based base material main component and an accessory component including dysprosium (Dy) and terbium (Tb),
a content of terbium (Tb) is 0.2 mol or more and less than 1.0 mol based on 100 mol of the base material main component, and
the dielectric layers include a plurality of dielectric crystal grains having a particle size of 60 nm or more and 250 nm or less at a point (D50) at which a cumulative volume is 50% in a cumulative particle size distribution according to a particle size distribution system.
