" summary "
By summarizing above-mentioned 1st to the 5th embodiment it can be found that its core is, relative at least one
At least one of at least one conductor openings portion CW possessed by coil-conductor 12, under overlooking state, magnetic material core 20 with
Conductor openings portion CW overlapping, and it is only Chong Die with a part in coil-conductor portion for surrounding conductor openings portion CW.Above-mentioned
In embodiment, conductor plate 40 is the tabular that edge does not have metallic walls.At this point, the not coil Chong Die with magnetic material core 20
Conductor portion, which is at least, to be surrounded in the coil-conductor portion of conductor openings portion CW, far from the upper of the close side of institute of the conductor openings portion
State the part at the edge of conductor plate 40.As long as also, at least one conductor openings portion CW meets this condition.
However, the edge of conductor plate 40 may have metallic walls in actual design.Figure 19 (A) show the above-mentioned 1st to
The configuration mode of magnetic material core 20 shows when 5th embodiment is such, conductor plate 40 is tabular of the edge without metallic walls
Be intended to, Figure 19 (B)~Figure 19 (D) show conductor plate 40 edge be equipped with metallic walls 41 when magnetic material core 20 configuration mode and
The schematic diagram of magnetic flux.
As shown in Figure 19 (A), there is no metallic walls 41 at 40 edge of conductor plate, it is in other words flat or be not provided with and obviously may be used
When shielding the structure of the magnetic line of force, magnetic material core 20 is configured by using configuration mode shown in above-mentioned 1st to the 5th embodiment,
That is, edge close to the coil-conductor of the coil-conductor portion not Chong Die with magnetic material core 20 far from conductor plate 40.At this point, magnetic flux
Can successfully it pass through via conductor openings portion and magnetic material core 20.
However, Figure 19 (B) like that, the edge of conductor plate 40 be equipped with metallic walls 41 in the case where, according to Figure 19 (A)

The part of edge, i.e. metallic walls 41, at this point, as shown in Figure 19 (C), due to 20 side of magnetic material core coil-conductor portion 12 with
Space between metallic walls 41 becomes larger, therefore magnetic flux bypasses metallic walls 41 more easily by the space compared with Figure 19 (B).By
This as it can be seen that the edge of conductor plate 40 be equipped with metallic walls 41 in the case where, with the case where no metallic walls 41 on the contrary, coil is led
When the part at the edge that part Chong Die with magnetic material core 20 is not close proximity to conductor plate 40 in body portion 12, good coupling can be obtained
It is right.
Preferably, if making magnetic material core 20 further to the side far from coil-conductor portion 12 (in figure as Figure 19 (D)
For left side) extend, then can further increase by magnetic flux quantity, to can be further improved the degree of coupling.
