Multilayer coil component

A multilayer coil component comprising:

• a multilayer body that includes a plurality of insulating layers laminated in a lamination direction and a coil inside the multilayer body;
• and
• an outer electrode that is at a surface of the multilayer body and electrically connected to the coil,
• wherein
• the multilayer body has a first end surface and a second end surface that face each other in a length direction, a first main surface and a second main surface that face each other in a height direction, which is perpendicular to the length direction, and a first side surface and a second side surface that face each other in a width direction, which is perpendicular to the length direction and the height direction,
• the outer electrode includes a first outer electrode extending from at least a portion of the first end surface of the multilayer body to a portion of the first main surface and a second outer electrode extending from at least a portion of the second end surface of the multilayer body to a portion of the first main surface,
• the outer electrode includes a base electrode including at least Ag and glass, and
• a diffusion length of the glass from an interface between the outer electrode and the multilayer body toward the multilayer body is from 2.44 μm to 6.90 μm.
