Claims (1)

[Claims for Utility Model Registration] (1) A tape electric wire in which a plurality of conductors are arranged in parallel and sandwiched between films forming a covering layer, in which the films forming the covering layer are two different types of films. A tape electric wire characterized in that it is a bonded insulating film in which similar pieces are alternately spliced in the longitudinal direction of the tape electric wire. (2) The tape electric wire according to claim 1, wherein one type of the bonded insulating film is a heat-resistant polyimide film, and the other film is a polyester film. (3) The insulating films of 1 and 2 above are two different types of films stacked alternately in the longitudinal direction,
The tape electric wire according to claim 1 or 2, characterized in that it is a bonded insulating film that is butted and spliced. (4) When forming a covering layer using the bonded insulating films of 1, 2, and 3 above, the films are pasted together so that the film parts made of the same material are in approximately the same position on the top and bottom surfaces of the covering layer. The tape electric wire according to any one of claims 1 to 3, characterized in that the tape electric wire is formed. (5) At least one end of the tape electric wire described in 1, 2, 3, and 4 above has a board connection area where one of the upper and lower surfaces has the conductor exposed, and the conductor is sandwiched between two heat-resistant films. Claims 1 to 4, characterized in that the film is cut so as to have an end portion consisting of a heat dissipating part, which is attached to the heat radiating part, and a heat shrinkage prevention part, in which one insulating film is adhesively fixed to the other heat resistant film. Tape wire as described in any one of the above. (6) Cut the tape electric wire described in 5 above so that both ends thereof have a coating layer with different film parts, and cover either the front or back of the heat-resistant film part located at one end with the internal conductor part. 6. The tape electric wire according to claim 5, wherein the tape electric wire is peeled off so that a sufficient length required for connection with the substrate is exposed. (7) Cut the tape electric wire of 5 above so that both ends thereof have a coating layer with different film parts, and connect either the front or back of the film parts at both ends with the internal conductor part to the board. 6. The tape electric wire according to claim 5, wherein the tape electric wire is peeled off so that a sufficient length required for the wire is exposed. (8) Cut the tape electric wire described in 5 above so that both ends thereof are covered with a heat-resistant film part, and either the front or back of the film part at one end or both ends is cut so that the internal conductor part is connected to the board. 6. The tape electric wire according to claim 5, wherein the tape electric wire is peeled off so as to be exposed to a sufficient length required for connection.
