CIRCUIT MODULE HAVING ATTACHED METAL CASE, CIRCUIT MODULE ASSEMBLY HAVING ATTACHED METAL CASE, AND METHOD FOR PRODUCING CIRCUIT MODULE HAVING ATTACHED METAL CASE

摘要

Provided is a more compact circuit module having an attached metal case. The circuit module having an attached metal case is characterized by being provided with: a circuit board having at least four sides; an electronic component mounted to the circuit board; and a metal case attached to the circuit board, covering the electronic component. The circuit module having an attached metal case is further characterized by a metal case land electrode for attaching the metal case being formed in the vicinity of a side on the surface of the circuit board, the metal case land electrode being provided with a main electrode section and a joining material supply section extending in the direction of the side of the circuit board from the main electrode section, and the metal case being joined to the main electrode section by means of the conductive joining material.
