The wiring board includes an insulating substrate having a main surface, an external electrode on the main surface and an outer edge portion of the insulating substrate, and a dissipating metal layer on the main surface of the insulating substrate, the dissipating metal layer having a greater area than the external electrode if viewed in a plan, the dissipating metal layer being adjacent to the external electrode and having a slit. The slit has an opening at an outer periphery of the dissipating metal layer. The external electrode faces the opening.

Wiring board, electronic device, and electronic module

A wiring board includes an insulating substrate, mount electrodes arranged to face each other on a first main surface of the insulating substrate along a pair of opposing sides of the insulating substrate in a plan view, and terminal electrodes arranged to face each other on a second main surface of the insulating substrate along another pair of opposing sides of the insulating substrate in a perspective plan view.

A light-emitter mounting package includes an insulating base, a wiring conductor, and a metal layer. The insulating base has a main surface including a recess in which a light emitter is mountable. The wiring conductor is arranged on a peripheral portion of a bottom surface of the recess that is adjacent to an inner wall of the recess. The insulating base has a side surface including a sloping surface adjacent to the main surface. The metal layer is spaced from the wiring conductor, and extends on the inner wall of the recess, the main surface, and the sloping surface.

Light-emitter mounting package, light-emitting device, and light-emitting module

A wiring board has an insulation base plate, and a plurality of electrodes provided adjacent to each other in plan view on the insulation base plate, the electrodes have an opening in the outer periphery and a slit oriented from the outer periphery to the interior, and, among two electrodes adjacent to each other, the slit in one electrode has a central line intersecting the outer periphery of the other electrode.
