Multilayer ceramic electronic component

A multilayer ceramic electronic component comprising:

• a component body of roughly rectangular solid shape having internal conductor layers and a pair of external electrodes provided on the component body and also connected to the internal conductor layers, wherein:
• when, of the six faces of the component body, a direction in which a first pair of faces are opposing each other is given as a first direction, a direction in which a second pair of faces are opposing each other is given as a second direction, and a direction in which a third pair of faces are opposing each other is given as a third direction,
• each of the external electrodes is constituted by a base part present on one first-direction face of the component body, and a first part, continuously from the base part, present at least on one third-direction face, among the one third-direction face, the other third-direction face, one second-direction face, and the other second-direction face, of the component body;
• and
• a group of metal grains is provided along the first direction of the component body over at least the other third-direction face, among the one third-direction face and the other third-direction face, of the component body,
• wherein a first-direction reference dimension of an area in which the group of metal grains is provided is the same as a first-direction reference dimension of the component body, and a second-direction reference dimension of the area is smaller than a second-direction reference dimension of the component body.
