Patent number: 11894195Abstract: An electronic component includes an element body, an external electrode, and a resin film having electrical insulation properties. The element body includes a principal surface and a side surface adjacent to the principal surface. The external electrode includes a first electrode portion disposed on the principal surface and a second electrode portion disposed on the side surface. The resin film is disposed on the principal surface and is in contact with the principal surface. Each of the first electrode portion and the second electrode portion includes a conductive resin layer disposed on the element body. A conductive resin layer included in the first electrode portion is disposed on the resin film and is in contact with the resin film.Type: GrantFiled: November 8, 2021Date of Patent: February 6, 2024Assignee: TDK CORPORATIONInventors: Yoji Tozawa, Masashi Shimoyasu, Makoto Yoshino, Takuo Abe, Akihiko Oide, Tsutomu Ono, Shinichi Sato, Makoto Morita, Shinichi Sato, Hidekazu Sato

Patent number: 11631521Abstract: An electronic component includes an element body and an external electrode disposed on the element body. The external electrode includes an underlying metal layer, a conductive resin layer, and a plating layer. The underlying metal layer is disposed on the element body. The conductive resin layer contains a plurality of conductive fillers and is disposed on the underlying metal layer. The plating layer is disposed on the conductive resin layer. A part of the plurality of conductive fillers is sintered with the underlying metal layer and is coupled to the underlying metal layer. Another part of the plurality of conductive fillers is exposed to a surface of the conductive resin layer and is in contact with the plating layer.Type: GrantFiled: April 29, 2019Date of Patent: April 18, 2023Assignee: TDK CORPORATIONInventors: Yoji Tozawa, Takuo Abe, Yuma Ishikawa, Hidekazu Sato, Takashi Endo, Masashi Shimoyasu, Kazuma Takahashi
