PROBLEM TO BE SOLVED: To provide an electronic device for inrush current limiting made of an NTC ceramic material having an electric resistance in the mΩ region at a temperature of 25 ° C. and / or room temperature. An NTC ceramic has a composition of La (1-x) EA (x) Mn (1-a-bc) Fe (a) Co (b) Ni (c) O (3 ± δ). Here, 0 ≦ x ≦ 0.5, 0 ≦ (a + b + c) ≦ 0.5, and δ is | δ | ≦ 0.5, and the electronic device is monolithic and has a thickness of 1.0 mm or less. Has. [Selection diagram] None |
