Ceramic wiring components

Abstract

[Problem] The present invention aims to provide a ceramic wiring component having a pair of internal terminals capable of mounting electronic components, and easily forming other wiring in the region outside the pair of internal terminals in the arrangement direction of the pair of internal terminals. [Solution] A ceramic wiring component with a temperature sensor mounted thereon, the ceramic wiring component comprising: a body portion having: a ceramic plate-shaped portion; a ceramic frame portion erected from the plate-shaped portion to surround a space on one main surface of the plate-shaped portion, i.e., a cavity in which the temperature sensor is disposed; and a conductive portion disposed in contact with the body portion. The conductive portion comprises: a pair of internal terminals spaced apart in a first direction in a region facing the cavity on one main surface of the plate-shaped portion, and in which the temperature sensor is disposed; a plurality of external terminals disposed on a surface different from the surface in which the pair of internal terminals are formed; and a plurality of wiring portions electrically connecting each internal terminal to each external terminal. Each wiring portion includes: an exposed wiring portion located in a region facing the cavity on one of the main surfaces of the plate-shaped portion; and a covered wiring portion forming at least a portion of a conductive path from the exposed wiring portion to an external terminal, and formed within the body portion. The exposed wiring portion of at least one wiring portion protrudes from the outer edge of the corresponding internal terminal along a side edge in a first direction.
