To provide a device for fixing a wiring code terminal which realizes easy fixing operation of a code terminal part and also enables a code after fixed to be readily taken around.

In a device wherein a terminal part of wiring codes 15A, 15B, which are formed by covering a linear conductor 11 with a skin member 13 formed of an insulator, is fixed to an electric circuit substrate 30 in a prescribed position by a fixing plate 20 which locks into the skin member 13, the fixing plate 20 has a base end part 21 supported by the electric circuit substrate 30 and a holding part 22 holding a terminal part 13a of the skin member 13 at a position spaced a prescribed clearance away from the base end part 21. The terminal part 13a of the skin member 13 is held by the holding part 22 at a tilting fixing position whose direction is close to a normal V of a plate face 31 of the substrate 30 than the plate face 31. Thereby, the linear conductor 11, which projects from the skin member 13 and is connected to the substrate 30, is prevented from bending at an acute angle.
