Multilayer electronic component

A multilayer electronic component comprising:

• a multilayer body comprising multiple inner electrodes and multiple dielectric layers alternately stacked, and comprising a first surface and a second surface opposed to each other in a stacking direction and a wall surface facing a specified direction intersecting the stacking direction;
• multiple underlying electrodes;
• and
• multiple outer electrodes, wherein
• the multiple outer electrodes comprise a first outer electrode extending from the wall surface at least onto the first surface,
• the first outer electrode comprises:
• a first portion connected to an inner electrode exposed on the wall surface, out of the multiple inner electrodes;
• and
• a second portion connected to an underlying electrode located on the first surface, out of the multiple underlying electrodes, and
• an average particle diameter of metal particles in the first portion, at a position that is a first specified distance away in the specified direction from a surface on a multilayer body side, where the multilayer body is located, is smaller than an average particle diameter of metal particles in the second portion, at a position that is the first specified distance away in the stacking direction from a surface on the multilayer body side.
