Abstract: A multilayer ceramic electronic component includes an end surface of a second external electrode and an end surface of a fourth external electrode that face a mounting surface of a mounting substrate on which a first multilayer ceramic electronic component body and a second multilayer ceramic electronic component body are mounted. A first metal terminal is connected to the second external electrode, a second metal terminal is connected to the fourth external electrode, and a connection terminal is connected across a first external electrode and a third external electrode. An insulator is disposed between the first multilayer ceramic electronic component body and the second multilayer ceramic electronic component body.

Abstract: A multilayer ceramic electronic component includes a rectangular parallelepiped stacked body having first and second main surfaces and first and second end surfaces, and first and second external electrodes. The first external electrode is provided on a portion of the second main surface and on the first end surface, and the second external electrode is provided on a portion of the second main surface and on the second end surface. A semiconductor layer is provided at the interface between the stacked body and a portion of the first external electrode that is located on the portion of the second main surface, and a semiconductor layer is provided at the interface between the stacked body and a portion of the second external electrode that is located on the portion of the second main surface.

Abstract: A gas sensor includes a detection element for detecting a gas component of a gas to be measured, a casing for holding the detection element and a seal member forming a reference gas space together with the casing. The seal member has an end surface exposed to the atmosphere and a through-hole for establishing communication between the atmosphere and the reference gas space. A cylindrical insert member is inserted in the through-hole of the seal member. A sheetlike air permeable filter is sandwiched between an inner surface of the through-hole of the seal member and the cylindrical insert member so as to cover an atmosphere side opening portion of the cylindrical insert member. The atmosphere side opening portion of the cylindrical insert member is retracted from the end surface of the seal member toward the interior of the through-hole, whereby an atmosphere side face of the air permeable filter is retracted from the end surface of the seal member.
