    Abstract: The invention relates to a printed circuit comprising a substrate (1) onto which at least one ceramic component (2, 3, 4) is attached so as to enable the heat produced by the ceramic component (2, 3, 4) to be discharged and to prevent cracks in the ceramic component (2, 3, 4) and in the substrate (1). To this end, the ceramic component (2, 3, 4) is attached onto the substrate (1) by means of two connectors (5, 6) made of metal matrix composite material. Said two connectors further preferably have incisions so as to enable the mechanical stresses exerted in the substrate to be carried over into the connectors.

    Abstract: An electronic component, which is surface-mounted on a wiring board by soldering, and in which the occurrence of cracks in the solder after surface-mounting is suppressed, comprises: a member constituting at least part of a container and made of ceramic; and an external terminal provided on the outer surface of the member and used in surface-mounting the electronic component on the wiring board by solder. The film thickness of a layer constituting the external terminal is designed so that when the thermal expansion coefficient of the ceramic constituting the member is α 1 , combined expansion coefficient α k of the member and the external terminal satisfies a relation of 1.029≤α k /α 1 ≤1.216. The external terminal preferably comprises a nickel layer as an electrode body.
