Patent number: 9692156Abstract: An electronic device includes a substrate, and a press-fit terminal. The substrate includes a first surface, a second surface opposite to the first surface in a thickness direction of the substrate, a through hole, and an electrode formed in the first surface, the second surface, and a wall of the through hole. The press-fit terminal is fit into the through hole from the first surface while being elastically deformed. The press-fit terminal is connected to the electrode by a reaction force due to the elastic deformation of the press-fit terminal. The substrate includes (i) a core layer that is overlapped, in the thickness direction, with a contact portion of the electrode with the press-fit terminal, and (ii) a flexible layer that is at a position closer to the first surface than the core layer is to. The flexible layer has a lower elastic modulus than the core layer.Type: GrantFiled: July 1, 2016Date of Patent: June 27, 2017Assignee: DENSO CORPORATIONInventors: Eiichi Matsumoto, Yoshio Hironaka
