The cross sectional shape (referring to Fig. 3) orthogonal with extending direction X of the insulator 12,22 of present embodiment is formed substantially rectangular frame
Shape (the substantially shape of " ロ ").
Moreover, conductor 11 and conductor 21 extend in same extending direction X mutually, also, in cable 10 and cable 20 with phase
For opposed direction Z just positional relationship integration arranged opposite over the ground, it is routed in vehicle 100.Cable 10 and cable 20 are usual
In the case of it is opposed relative to this with opposed faces 11a, 21a in conductor 11 and conductor 21 relative to opposed direction Z and opposite one another

Any of the conditional (1) stated, (2), (3) and arranged opposite, when so as to flow through electric current near conductor 11,21
The magnetic field of generation is relatively effectively cancelled out each other, and suitably inhibits the influence in magnetic field.Fig. 5 is compared in present embodiment
The magnetic flux density in the magnetic field that the flat cable 1 being related to generates is produced with the circular cross-section cable CE (referring to Fig. 6) being related in comparative example
The curve graph of the magnetic flux density in raw magnetic field is represented as an example in the distance [mm] apart from conductor and 100A's
The relationship between magnetic flux density [T] generated when direct current power flows through.In Fig. 5, line L11 indicates the magnetic field that flat cable 1 generates
Magnetic flux density, line L12 indicate circular cross-section cable CE generate magnetic field magnetic flux density.Herein, the circle that comparative example is related to
O. cable CE is as illustrated in fig. 6, has and extends each other in the same direction and the cross sectional shape orthogonal with extending direction is by shape
As roughly circular a pair of conductors CE1, CE2, which is configured to relative to the width with flat cable 1
It is arranged opposite to spend the comparable direction direction Y.In the same manner as conductor 11,21, not shown insulator covers by a pair of conductors CE1, CE2
Lid peripheral side.Moreover, electric current is in conductor CE1, CE2 along the mutual reverse flow of extending direction X for circular cross-section cable CE
It is dynamic.
In this case, in the circular cross-section cable CE that comparative example is related to, when electric current in conductor CE1, CE2 along prolonging
When stretching the mutual reverse flow of direction X, the magnetic field generated in conductor CE1 and the magnetic field generated in conductor CE2 are reinforced mutually, such as
Shown in the line L12 of Fig. 5, near the conductor CE1, CE2, magnetic flux density has the tendency that relatively heightening.On the other hand, at this
In the flat cable 1 that embodiment is related to, when electric current reverse flow mutual along extending direction X in conductor 11,21, leading
The magnetic field generated in body 11 offsets each other with the magnetic field generated in conductor 21, as shown in the line L11 of Fig. 5, the conductor 11,
Near 21, magnetic flux density has the tendency that opposite be lower.
Moreover, Fig. 7 is one of the relationship between the conductor width W and magnetic flux density shown relative to conductor thickness T=1
The curve graph of example illustrates the direct current of the conductor width W and 100A relative to conductor thickness T=1 as an example
Relationship between the magnetic flux density [mT] of the out-of-date generation of force flow.In Fig. 7, line L21 indicates the magnetic flux in the magnetic field that flat cable 1 generates
Density, line L22 indicate the magnetic flux density in the magnetic field that circular cross-section cable CE is generated.Herein, magnetic flux density in flat cable 1
The P1 that locates is as illustrated in fig. 8, is conductor arranged opposite relative to opposed direction Z on the upside of the vertical direction on floor 110
11, near the surface with 110 opposite side of floor of the conductor 11 in 21.On the other hand, the magnetic flux in circular cross-section cable CE is close
The P2 that locates of degree is as illustrated in fig. 9, is arranged opposite relative to width direction Y on the upside of the vertical direction on floor 110
The central location in width direction Y in conductor CE1, CE2 near 110 opposite side of floor.Under normal conditions, electric current is one
To the magnetic flux density in magnetic field generated when being flowed in conductor 11,21 as shown in the line L21 of Fig. 7, shown in the line L22 of Fig. 7
Magnetic flux density in circular cross-section cable CE is compared, and is cancelled out each other relative to conductor thickness T-phase to longer there are conductor width W
Degree it is relatively higher, the magnetic flux density is relative to lower tendency.
In addition, Figure 10 is the conductor width W, distance between conductors D and magnetic flux density indicated relative to conductor thickness T=1
Between the curve graph of relationship illustrate the conductor width W relative to conductor thickness T=1, conductor spacing as an example
From the relationship between D and the magnetic flux density [mT] generated in the direct current power flowing of 100A.In Figure 10, line L31 expression is led
The magnetic flux density in the magnetic field that flat cable 1 generates when distance D is 1 times of conductor thickness T between body, line L32 indicate distance between conductors D
The magnetic flux density in the magnetic field that flat cable 1 generates when being 3 times of conductor thickness T, line L33 indicate that distance between conductors D is that conductor is thick
The magnetic flux density in the magnetic field that flat cable 1 generates when spending 5 times of T.Line L34 indicates the magnetic in the magnetic field that circular cross-section cable CE is generated
Flux density.Flat cable 1, magnetic field in circular cross-section cable CE magnetic flux density locate P1, P2 and phase the case where Fig. 7
With (referring to Fig. 8, Fig. 9).Under normal conditions, electric current flows through the magnetic flux density such as Figure 10 in the magnetic field generated when a pair of conductors 11,21
Line L31, L32, L33 shown in, compared with the magnetic flux density in the circular cross-section cable CE shown in the line L34 of Figure 10, exist
Distance between conductors D is relative to conductor thickness T-phase to shorter, and the degree cancelled out each other is relatively higher, and magnetic flux density is relatively lower
Tendency.As being substantially inclined to, the magnetic flux density in the magnetic field that the conductor 11,21 of flat cable 1 nearby generates is circular cross-section cable
About the 1/3 of the magnetic flux density in the magnetic field that conductor CE1, CE2 of CE is nearby generated is hereinafter, for example, be conductor thickness in conductor width W
In the case that 10 times or so and distance between conductors D of T are 1 times or so of conductor thickness T, about 1/10 or so, in conductor width W
In the case that 30 times or so and distance between conductors D for conductor thickness T are 1 times or so of conductor thickness T, about 1/20 or so.
For example, by circular cross-section cable CE configuration under the floor on the floor 110 formed by metal material when the floor 110 floor
On magnetic flux density exist reach circular cross-section cable CE conductor CE1, CE2 nearby generate magnetic field magnetic flux density about 1/
8~about 1/10 or so tendency.In contrast, it is known that, for the flat cable 1 of present embodiment, even if there be no as magnetic
The floor 110 formed by metal material etc. of field shield member is also realized and near conductor 11,21 by the circular cross-section cable
Magnetic flux density inhibitory effect more than the underfloor situation that CE configured on the floor 110 formed by metal material is same.In addition,
It will also realize that according to Fig. 7, Figure 10 etc., the flat cable 1 of present embodiment is on about 5~10 times of left sides that conductor width W is conductor thickness T
In right range, there are the point of inflexion (points of slope variation) for change in magnetic flux density.
In view of these tendencies, a pair of conductors 11,21 passes through full with conductor width W, conductor thickness T and distance between conductors D
The mode of sufficient conditional (1), that is, conductor width W is 5 times or more and 100 times or less and distance between conductors D of conductor thickness T
Formed greater than 0 and for 3 times of modes below of conductor thickness T, and arranged opposite, so as to will when electric current flows through conductor
11,21 magnetic fields nearby generated are more effectively cancelled out each other, and suitably inhibit the influence in magnetic field.In other words, a pair of conductors
11,21 in the case where conductor width W is 5 times or more of conductor thickness T and 100 times of situations below, if distance between conductors D compares conductor
3 times of thickness T are longer, then the degree cancelled out each other in magnetic field is opposite becomes smaller, and there are the inhibitory effects of the influence in magnetic field relatively not
The tendency of foot.On the contrary, a pair of conductors 11,21 is in 3 times or less of the situation that distance between conductors D is greater than 0 and is conductor thickness T
Under, if conductor width W is less than 5 times of conductor thickness T, the degree cancelled out each other in magnetic field is opposite to become smaller, and there are magnetic fields
The tendency of the inhibitory effect relative deficiency of influence.
In addition, a pair of conductors 11,21 is by meeting conditional with conductor width W, conductor thickness T and distance between conductors D
(2) mode, that is, conductor width W is 10 times of conductor thickness T or more and 100 times or less and distance between conductors D is greater than 0 and is
5 times of modes below of conductor thickness T are formed, and arranged opposite, thus compared with conditional (1), it will be relative to conductor thickness
The conductor width W for spending T is relatively elongated, on the other hand, distance between conductors D can allow for relatively to broaden.In addition, a pair of conductors
11, the magnetic field that 21 conductors 11,21 when can flow through electric current nearby generate more effectively cancels out each other and suitably inhibits magnetic
The influence of field.That is, a pair of conductors 11,21 is below in 10 times or more and 100 times that conductor width W is conductor thickness T
In the case of, even if distance between conductors D is longer than 3 times of conductor thickness T, as long as 5 times of conductor thickness T hereinafter, can then fit
Locality inhibits the influence in magnetic field.A pair of conductors 11,21 is greater than 0 in distance between conductors D and is 5 times of conductor thickness T conversely speaking,
In situation below, if 10 times of conductor width W deficiency conductor thickness T, the degree cancelled out each other in magnetic field relatively becomes
Small, there are the tendencies of the inhibitory effect relative deficiency of the influence in magnetic field.
Further, a pair of conductors 11,21 is by meeting item with conductor width W, conductor thickness T and distance between conductors D
The mode of part formula (3), that is, conductor width W be (the 3+ distance between conductors D/ conductor thickness T) times of conductor thickness T or more and 100 times with
Lower and distance between conductors D is greater than 0 and is formed for 5 times of modes below of conductor thickness T, and arranged opposite, thus with item
Part formula (1), (2) are compared, can using the conditional of conductor width W as the combination of distance between conductors D and conductor thickness T, and
Balance adjusts the combination of distance between conductors D, conductor thickness T and conductor width W well.In addition, a pair of conductors 11,21 can incite somebody to action
The magnetic field that conductor 11,21 nearby generates when electric current flows through more effectively is cancelled out each other, and inhibits the influence in magnetic field.
Further, it is further preferred that a pair of conductors 11,21 is with conductor width W, conductor thickness T and distance between conductors D
The mode for meeting following conditional (4) is formed and arranged opposite.That is, a pair of conductors 11,21 is more preferably wide with conductor
Degree W is 10 times of conductor thickness T or more 100 times or less and distance between conductors D greater than 0 and is 3 times of conductor thickness T below
Mode is formed and arranged opposite.In this case, conductor 11,21 nearby produces when a pair of conductors 11,21 can flow through electric current
Raw magnetic field is more effectively cancelled out each other, and further suppresses the influence in magnetic field.
