摘要: A laminate is prepared in which adjacent internal electrodes are electrically insulated from each other at an end surface at which the internal electrodes are exposed, a space between the adjacent internal electrodes, which is measured in the thickness direction of insulating layers, is about 10 μm or less when a withdrawn distance of the adjacent internal electrodes from the end surface is about 1 μm or less, and is about 20 μm or less when a protruding length of the adjacent internal electrodes from the end surface is at least about 0.1 μm. In an electroplating step, electroplating deposits deposited on the ends of the adjacent internal electrodes are grown so as to be connected to each other.

摘要: A method for manufacturing a laminated electronic component is performed such that a water-repellent agent is applied to end surfaces at which ends of internal electrodes are exposed so as to be filled in spaces along interfaces between insulating layers and the internal electrodes. Subsequently, an abrading step is performed such that the internal electrodes are sufficiently exposed at the end surfaces and an excess water-repellent agent is removed therefrom to enable plating films to be directly formed on the end surfaces.

摘要: A composite laminate includes first sheet layers and second sheet layers. The first sheet layers include a first particulate aggregate and the second sheet layers include a second particulate aggregate. Each of internal second sheet layers is disposed between two first sheet layers and two external second sheet layers constitute two main faces of the composite laminate. The thickness of the internal second sheet layers is greater than the thickness of the external second sheet layers. The first sheet layers and the second sheet layers are bonded to each other by penetration of a part of the first particulate aggregate contained in the first sheet layers into the second sheet layers. This configuration can reduce the transverse shrinkage in the firing step of the composite laminate.
