Patent ID: 7232958

Claim:
A circuit substrate component fixing apparatus, comprising: a circuit substrate on which a component is to be mounted to form an electronic circuit; a mounting component mounted on the circuit substrate and having a package including an electronic component and an external lead for providing connection between the electronic component and the circuit substrate; and a holder for holding the mounting component, which is fixed to the circuit substrate and made from an insulating material, wherein the holder is provided with a holding unit for holding and fixing the package of the mounting component and a lead hole for guiding the external lead to a through hole of the circuit substrate, wherein the holding unit comprises a first substantially flat surface opposing a second substantially flat surface which each, respectively, contact opposing surfaces of the mounting component, a third substantially flat surface parallel to the second substantially flat surface, wherein the second substantially flat surface and the third substantially flat surface each contact only a portion of a same opposing surface of the mounting component.
