A structure for fixing an electric circuit is provided to prevent the electric circuit from being damaged by inserting a pressing protrusion into a recessed groove formed on an upper plane of a rib formed on an insulation plate. A structure for fixing an electric circuit includes a rib(32), an insulation plate(30), an electric circuit(20), a recessed groove(34), a pressing protrusion(42), and a stepped protrusion(44). The rib(32) is protrusively formed on the insulation plate(30). The rib(32) is inserted into a fixing hole of the electric circuit(20). The insulation plate(30) and the electric circuit(20) are fixed by pressing the rib(32) from an upper part through an pressure rod and deforming the rib(32) permanently. The recessed groove(34) is recessed on an end plane of the rib(32) and gets narrow as going to an lower part. The pressing protrusion(42) of a corn shape is inserted into the recessed groove(34) on an end plane of the pressing rod. The stepped protrusion(44) is formed on an outer side of the pressing protrusion(42).
