An electronic device includes an element body. The element body includes at least two internal electrode layers and a dielectric layer laminated between the internal electrode layers. Ni oxide particles exist at a boundary between the internal electrode layers and the dielectric layer. The dielectric layer is in contact with the internal electrode layers at first and second boundaries. The dielectric layer includes a first dielectric large particle and a second dielectric large particle. The first dielectric large particle is in contact with at least one of the Ni oxide particles existing at the first boundary and in contact with one of the internal electrode layers at the second boundary. The second dielectric large particle is in contact with at least one of the internal electrode layers at the first boundary and in contact with at least one of the Ni oxide particles existing at the second boundary.
