<p>Provided is an electric circuit structure that solves the problem that a flexible substrate fixed to the back surface of a mechanical member becomes separated due to a repulsive force generated at a folded part of the flexible substrate that is connected to a circuit board. The structure is provided with a frame-shaped mechanical member (9) with a bottom; a circuit substrate (1) that is housed inside the mechanical member (9) and has electric circuit elements formed on the surface of the substrate; and a flexible substrate (10) that is folded along a folding part (10b) on the side surface of the mechanical member (9) while a connection terminal formed on one end (10a) is connected to an electrode terminal (7) formed on the circuit substrate (1), and the other end (10c) opposite the aforementioned one end (10a) is fixed to the back surface of the mechanical member (9). A deformation prevention material (11), that is cured by means of ultraviolet rays or heat, is coated on the outer side surface of the folding part (10b) of the flexible substrate (10) after the flexible substrate (10) is folded.</p> |
