PROBLEM TO BE SOLVED: To provide wiring board and an electronic apparatus, which easily improve reliability on connection to an external electric circuit.SOLUTION: A wiring board comprises: an insulating substrate 1 which has a top face including a mounting part 1a of an electronic component 3, an undersurface and a plurality of lateral faces; and a plurality of side conductors 2 provided on at least one lateral face of the insulating substrate 1 from a bottom edge of the at least one lateral face in an upward direction. The lateral face of the insulation substrate 1 where the side conductors 2 are provided has one cavity 6 at a central part in a width direction, which extends from the bottom edge in an upward direction and all of the plurality of side conductors 2 provided on the one lateral face is arranged in the one cavity 6. A distance from a central part of the insulating substrate 1 to the side conductor 2 is decreased and thermal stress acting on a connection part of the side conductor 2 and an external electric circuit is reduced thereby to improve connection reliability. |
