Abstract: An NTC thermistor element includes a thermistor body and a plurality of internal electrodes disposed in the thermistor body and opposing each other. The thermistor body includes a region interposed between adjacent internal electrodes of the plurality of internal electrodes. The region of the thermistor body includes a plurality of crystal grains arranged in succession between the internal electrodes adjacent to each other. The plurality of crystal grains include a first crystal grain, a second crystal grain, and a third crystal grain. The first crystal grain is in contact with one internal electrode of the internal electrodes adjacent to each other. The second crystal grain is in contact with another internal electrode of the internal electrodes adjacent to each other. The third crystal grain is not in contact with the first crystal grain and the second crystal grain.

Abstract: An NTC thermistor element is of less than 0402 size. A first internal electrode is connected to a first external electrode. A second internal electrode is separated from the first internal electrode and is connected to a second external electrode. A third internal electrode opposes the first and second internal electrodes and is not connected to the first external electrode and the second external electrode. A shortest distance between the first internal electrode and the third internal electrode and a shortest distance between the second internal electrode and the third internal electrode are smaller than a shortest distance between the first internal electrode and the second internal electrode, a shortest distance between the first external electrode and the third internal electrode, and a shortest distance between the second external electrode and the third internal electrode, and are less than or equal to ¼ the thickness of the thermistor body.

Abstract: An electronic component has an element body, and a plurality of external electrodes formed on one principal face of the element body. Each external electrode has a first electrode layer joined to the one principal face of the element body, and a second electrode layer joined as laid on an inside region inside an edge of the first electrode layer. An apical surface of the second electrode layer is planar. A joint portion in the second electrode layer to the first electrode layer is rounded.
