<P>PROBLEM TO BE SOLVED: To provide a circuit board assembly that can optimize the height of a circuit element with a simple structure. <P>SOLUTION: An element attachment part 11, to which a light receiving element 100 is attached, is formed so that the outer periphery thereof is disposed apart from a remainder 10a of a circuit board 10. The circuit board 10 includes a coupling part 12 that connects a part of the outer periphery of the element attachment part 11 and the remainder 10a of the circuit board 10 and deflects to allow the movement of the element attachment part 11 in the thickness direction of the circuit board 10. On the side opposite to the light receiving element 100 beyond the element attachment part 11, a pedestal 30 is disposed that pushes the element attachment part 11 upwardly in the thickness direction of the circuit board 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
