  • Patent number: 10074465
    Abstract: 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.
