<P>PROBLEM TO BE SOLVED: To provide a circuit structure which can be adapted to high-density mounting on a board and can be used for a high-current circuit, and also to provide an electrical connection box. <P>SOLUTION: A circuit structure 20 comprises: a circuit board 21 on which electronic components 22 are mounted; and a conductive plate 30 attached to one face 21A of the circuit board 21. A plurality of attachment holes 25 for attaching the conductive plate 30 are provided on the circuit board 21 such that the holes penetrate through both faces of the circuit board 21. A conductive plate body 31 and board attachment parts 34 are integrally provided on the conductive plate 30. The board attachment parts 34 are formed in a manner extending from the conductive plate body 31 to the circuit board 21 side and are attached into the attachment holes 25 on the circuit board 21. Further, the board attachment parts 34 are each provided with a contact portion 35 which comes into contact with the one face 21A of the circuit board 21 and a pair of attachment pieces 36, 36. The pair of attachment pieces 36, 36 are provided to extend from the contact portion 35, and they are inserted through the attachment holes 25 and folded so as to be in contact with the other face 21B of the circuit board 21, thereby sandwiching and fixing the circuit board 21 together with the contact portion 35. <P>COPYRIGHT: (C)2012,JPO&INPIT |
