Abstract
A wiring board includes an insulation layer made of a ceramic, and an electrical conductor layer extending in a planar direction inside the insulation layer. The electrical conductor layer is constituted by a sintered body of a plurality of crystallites containing a metal as a main component. When a specific range of the electrical conductor layer is specified in a cross-sectional view, a linear length in the planar direction is defined as L0, and a length of a contour of the electrical conductor layer is defined as L1, L1/L0 is within a range from 1.04 to 1.40.
