Zusammenfassung:To provide a multi-terminal multilayer ceramic capacitor having three or more terminals, for which it is easy to apply a technique of disposing a side gap part at a later time.SOLUTION: The multilayer ceramic capacitor comprises a laminate in which a first dielectric layer and a second dielectric layer are alternately laminated, the laminate having two principal surfaces, two side surfaces and two end surfaces. The laminate includes an inner layer part in which a first internal electrode and a second internal electrode are alternately laminated via the dielectric layer, outer layers which are arranged so as to sandwich the inner layer in the laminate direction and are composed of a dielectric material, and side gap parts which are arranged so as to sandwich the inner layer and outer layers in the width direction, and is provided with a first external electrode connected to the first internal electrode and a second external electrode connected to the second internal electrode. The first external electrode includes a principal surface arranged electrode part which is disposed on at one of the two principal surfaces, and a side surface arranged electrode part which connects to at least one side surface side end of the first inner electrode and is covered with the side gap part.SELECTED DRAWING: Figure 1 【課題】サイドギャップ部を後から配置する手法の適用が容易な三端子以上の多端子の積層セラミックコンデンサを提供する。【解決手段】積層セラミックコンデンサは、第1誘電体層と第2誘電体層とが交互に積層された積層体を備え、積層体は、2つの主面、2つの側面及び2つの端面を有し、積層体は、第1内部電極及び第2内部電極が誘電体層を介して交互に積層される内層部と、内層部を積層方向に挟むように配置され、かつ、誘電体材料で構成される外層部と、内層部及び外層部を幅方向に挟むように配置されサイドギャップ部と、を有し、第1内部電極につながった第1外部電極と、第2内部電極につながった第2外部電極と、を備え、第1外部電極は、2つの主面の少なくとも一方に配置された主面配置電極部と、第1内部電極の少なくとも一方の側面側端部につながり、サイドギャップ部に覆われた側面配置電極部と、を有する。【選択図】図1
