Title:
MULTILAYER CERAMIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2024/014176
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a multilayer ceramic capacitor (1) in which a decrease in moisture resistance can be inhibited, while having a small size and a high capacity. The multilayer ceramic capacitor (1) includes a first corner portion (C1) that curves across a first main surface (M1) and a first main portion side surface (SS1) of a capacitor main portion (3), a second corner portion (C2) that curves across a second main surface (M2) and the first main portion side surface (SS1), a third corner portion that curves across the first main surface (M1) and a second main portion side surface (SS2), and a fourth corner portion (C4) that curves across the second main surface (M2) and the second main portion side surface (SS2). A first insulating portion (8a) covers the first corner portion (C1) and the second corner portion (C2), and a second insulating portion (8b) covers the third corner portion (C3) and the fourth corner portion (C4). The roughness of the first corner portion (C1) is greater than that of a first outside corner portion (K1), the roughness of the second corner portion (C2) is greater than that of a second outside corner portion (K2), the roughness of the third corner portion (C3) is greater than that of a third outside corner portion (K3), and the roughness of the fourth corner portion (C4) is greater than that of a fourth outside corner portion (K4).
