    Abstract: [Problem] To provide a highly-reliable circuit board and an electronic device obtained by mounting electronic components on the circuit board, which have high bonding strength and excellent heat discharge properties, and can be used over a long period as a result of minimizing cavities in a metal wiring layer formed on a through conductor. [Solution] A circuit board (10) is provided with a through conductor (13) comprising a metal in a through hole (12) that penetrates in the thickness direction of a ceramic sintered body (11), and a metal wiring layer (14) that covers and is connected to the surface of the through conductor (13) on at least one main surface side of the ceramic sintered body (11). The through conductor (13) comprises: a first portion (13a) that is positioned on an inner wall side of the through hole (12), from one end to the other end of the through hole (12) in the thickness direction of the ceramic sintered body (11); and a second portion (13b) that adjoins the first portion (13a). The average crystal grain size in the second portion (13b) is larger than the average crystal grain size in the first portion (13a).

    Abstract: A connecting terminal has a configuration in which a plurality of parts of a first line (2) and respective corresponding plurality of parts of a second line (6) are connected to each other by a transparent conductive thin film (10). In a connecting terminal part, the plurality of parts of the first line (2) and the respective corresponding plurality of parts of the second line (6) are connected to each other in parallel. With the configuration, it is possible to greatly reduce a risk of disconnection. It is therefore possible to prevent disconnection from being caused by corrosion in the connecting terminal part of a display apparatus etc.
