摘要： A thermistor element satisfies 4≦(d/ed) when a first distance is d, which is a shortest distance between a first internal electrode and a second external electrode, whereas a second distance is referred to as ed, which is a shortest distance between the first internal electrode and a fifth internal electrode, in a cross section of a body including an L direction and a T direction thereof.

摘要： A thermistor element includes an element body made of ceramic and including first and second end surfaces opposite to each other and a peripheral surface located between the first end surface and the second end surface, first and second external electrodes respectively covering the first and second end surfaces and portion of the peripheral surface adjacent to the respective first and second end surfaces. The first and second external electrodes include electrode layers including an underlayer and a metal plating layer, the underlayer of the first external electrode includes, adjacent to or in a vicinity of the second external electrode, two second external electrode side corner portions that are thin and adjacent to each other, and the underlayer of the second external electrode includes, adjacent to or in a vicinity of the first external electrode, two first external electrode side corner portions that are thin and adjacent to each other.

摘要： A method of manufacturing an electronic component includes manufacturing a ceramic element including one pair of end surfaces and four side surfaces, forming external electrodes at both end portions of the ceramic element, measuring an initial characteristic value, determining any side surface to be machined among the four side surfaces and then determining, based on stored data, an amount of machining to be performed on the side surface to be machined, and machining, by the determined machining amount, the side surface of the ceramic element, which is determined to be machined, to be flush or substantially flush with the external electrodes.
