Ceramic wiring components

Abstract

In a ceramic wiring member having a pair of internal terminals for mounting electronic components, the invention facilitates the formation of other wiring. [Solution] The ceramic wiring member 1 comprises a main body 2 having a plate-shaped portion and a frame portion 22, and a conductive portion 3. The conductive portion has a pair of internal terminals 43, 44 spaced apart in a first direction D1 within a region of one main surface of the plate-shaped portion facing the cavity 24, on which a temperature sensor 80 is placed, a plurality of external terminals 51 to 54 arranged on a surface different from the surface on which the pair of internal terminals are formed, and a plurality of wiring portions that electrically connect each internal terminal to each external terminal. Each wiring portion includes an exposed wiring portion 64 located within a region of one main surface of the plate-shaped portion facing the cavity, and a covered wiring portion 65 formed within the main body portion that forms at least a part of the conductive path from the exposed wiring portion to the external terminal. At least one exposed wiring portion protrudes from a side edge 443 along the first direction of the outer edge of the corresponding internal terminal.

Claims
