Abstract

To provide a laminated ceramic electronic component capable of miniaturization and surface mounting while suppressing creeping discharge and heat generation. The laminated ceramic electronic component (10A) of the present invention has: an electronic component main body (12) including a first external electrode (24a) arranged on a first side surface (14c) of a laminate (14); (24a) The second external electrode (24b) that is separately provided and arranged on the first side surface (14c); the first metal terminal (40A) connected to the first external electrode (24a); and the second external electrode (24b) a second metal terminal (40B) for connection; and an outer casing (15). The electronic component body (12) is arranged such that the first or second side (14c, 14d) faces the mounting surface of the mounting substrate, the first and second internal electrode layers (18a, 18b) are arranged approximately perpendicular to the mounting surface, and the second A part of one side surface (14c), first and second external electrodes (24a, 24b) and parts of first and second metal terminals (40A, 40B) are covered by an exterior member (15).

Description

technical field [0001] The present invention relates to a laminated ceramic electronic component including, for example, a laminated ceramic capacitor or the like. Background technique [0002] Conventionally, inverter circuits suitable for energy saving and high efficiency have been used in consideration of the environment. However, in recent years, the use voltage tends to be higher, and an inverter circuit corresponding to high voltage and large current tends to be required. [0003] Furthermore, when used at a high voltage, in electronic components such as multilayer ceramic capacitors, discharge between external electrodes (so-called creeping discharge) tends to occur. Therefore, in a high-voltage inverter circuit, the creepage distance of discharge is regulated according to public standards. [0004] Due to such a requirement, in a high-voltage inverter circuit, even among capacitors, for example, the film capacitors described in Patent Document 1 and Patent Document...
