A method for manufacturing a multilayer ceramic electronic device includes punching out a ceramic sheet by one of left and right side surfaces of a laminated body so as to form a side margin part on the one of the left and right side surfaces of said laminated body; and punching out another ceramic sheet by another of the left and right side surfaces of the laminated body so as to form a side margin part on the another of the left and right side surfaces of said laminated body, thereby forming a ceramic main body having the laminated body and the pair of side margin parts that respectively cover the left and right side surfaces of the laminated body. The width W is greater than the length L in the multilayer ceramic electronic device.

Method for multilayer ceramic electronic device with punched out side margin parts

A method of producing a multi-layer ceramic electronic component includes: preparing a multi-layer unit including ceramic layers laminated in a direction of a first axis, internal electrodes disposed between the ceramic layers, and first and second side surfaces facing each other in a direction of a second axis orthogonal to the first axis, the internal electrodes being exposed from the first and second side surfaces; thermocompression-bonding a first side margin sheet to the first side surface; forming a first side margin by punching the thermocompression-bonded first side margin sheet with the first side surface; thermocompression-bonding a second side margin sheet to the second side surface, the second side margin sheet including a bonding surface having a higher flexibility than the first side margin formed on the first side surface; and forming a second side margin by punching the thermocompression-bonded second side margin sheet with the second side surface.

Method of producing a multi-layer ceramic electronic component and multi-layer ceramic electronic component

A multi-layer ceramic capacitor according to an embodiment of the present invention includes a multi-layer, side margins and offset sections. The multi-layer includes internal electrodes and dielectric layers alternately laminated. The side margins are configured of a dielectric and disposed to cover side faces of the multi-layer. The offset sections are made with amorphous areas or gap areas. The offset sections are formed between the internal electrodes and the side margins such that ends at side faces of the internal electrodes are offset from the side faces to an inward direction of the multi-layer.

Multi-layer ceramic capacitor and method of producing the same

A multi-layer ceramic capacitor includes a multi-layer unit and a side margin. The multi-layer unit includes ceramic layers laminated in a first direction and internal electrodes disposed between the ceramic layers. The side margin covers the multi-layer unit from a second direction orthogonal to the first direction and has a porosity of 1% or less.

A method of producing a multi-layer ceramic electronic component includes: preparing a multi-layer sheet including laminated ceramic sheets, and internal electrodes disposed between the ceramic sheets; cutting the multi-layer sheet to produce a multi-layer chip having a side surface from which the internal electrodes are exposed; removing a superficial layer of the side surface of the multi-layer chip; and providing a side margin to the side surface of the multi-layer chip, the superficial layer being removed from the side surface.
