<P>PROBLEM TO BE SOLVED: To provide a ceramic electronic component such as an inductor, in which the insulation performance can be secured even when fired simultaneously with a metal wire rod containing Cu as a main component, and which can have good electric properties. <P>SOLUTION: A metal wire rod 3 is embedded in a magnetic body part 2. A metal wire rod 13 is formed of an electrically conductive material containing Cu as a main component, and the magnetic body part 2 is formed of an Ni-Mn-Zn ferrite, in which when the molar content of CuO is ≤5 mol% and the molar content (x) of Fe<SB POS="POST">2</SB>O<SB POS="POST">3</SB>and the molar content (y) of Mn<SB POS="POST">2</SB>O<SB POS="POST">3</SB>are expressed by a coordinate point (x, y), the coordinate point (x, y) is in the range of coordinate points A (25, 1), B (47, 1), C (47, 7.5), D (45, 7.5), E (45, 10), F (35, 10), G (35, 7.5) and H (25, 7.5). <P>COPYRIGHT: (C)2013,JPO&INPIT |
