An inductor includes a core including a columnar shaft and a support on an end portion of the shaft, a terminal electrode disposed on the support, and a wire wound around the shaft and having an end portion connected to the terminal electrode. The terminal electrode includes a bottom surface electrode on a bottom surface of the support and an end surface electrode on an end surface of the support. The end surface electrode includes an end portion in a width direction of the end surface and a central portion in the width direction of the end surface. The central portion is positioned higher than the end portion.

Inductor

A multilayer ceramic electronic component that has a multilayer portion having an outer layer portion adjacent region including an area in contact with an outer layer portion that forms a thermal-shock absorbing portion that includes curved ceramic layers and inner electrode layers smoothly varying in thickness from point to point. A region to an inside of the thermal-shock absorbing portion forms a normal multilayer portion that includes ceramic layers with less curvature than the ceramic layers in the thermal-shock absorbing portion and inner electrode layers with less variation in thickness from point to point in a direction along a principal surface of the outer layer portion than the inner electrode layers in the thermal-shock absorbing portion.

Multilayer ceramic electronic component

An inductor including: a core having a winding core portion for winding a winding wire and two flange portions disposed on both ends of the winding core portion; and a winding wire wound around the winding core portion for multiple layers, the winding wire including: a forward winding layer having multiple turns on the winding core portion along a forward direction from one of the two flange portions toward the other flange portion; a backward winding layer following the forward winding layer and having at least one turn on the forward winding layer along a backward direction opposite to the forward direction; and a return winding portion following the backward winding layer and passing over the backward winding layer in the forward direction to reach the winding core portion on the forward direction side of the forward winding layer within less than 1/2 turn.

A piezoelectric element, which is capable of being driven with a relatively low voltage and obtaining a large displacement amount at a central portion thereof and is not degraded in characteristics over time and is easily mountable on or in a piezoelectric device, includes a piezoelectric body including a plurality of laminated piezoelectric layers, ground electrodes, central electrodes, and peripheral electrodes. A surface of the piezoelectric body includes first to fifth terminals. The extraction of the ground terminals, the central electrodes, and the peripheral electrodes to the first to fifth terminals is configured to connect one terminal of an alternating-current power supply to the third terminal and connect the other terminal of the alternating-current power supply to the first terminal and the second terminal.

Piezoelectric element and piezoelectric device using the same

A laminated ceramic capacitor including a laminated body having a plurality of stacked ceramic layers and internal electrodes located between the ceramic layers. The internal electrodes have a plurality of ceramic columnar members formed therein, which project into the internal electrodes from interfaces between the ceramic layers and the internal electrodes, but do not penetrate in the thickness direction of the internal electrodes.

Laminated ceramic electronic component and manufacturing method therefor

A holder for electroless plating to hold a plurality of ceramic elements for ceramic electronic parts during electroless plating treatment, each surface of said ceramic elements being to be electroless plated, said holder comprising a plurality of cells to house each of said plurality of ceramic elements separately, and each of said cells having such a structure as to permit the flow communication of a plating solution into the cell.
