Speech, if thickness variation occurs in the part for being formed relatively thin, the rate of change of thickness becomes big, surface mountable member (roundabout component
22 etc.) amplitude of fluctuation of the parasitic capacitance produced between coil-conductor 10 also becomes big.Therefore, in order to reduce roundabout component 22 with
The amplitude of fluctuation (deviation) of the parasitic capacitance produced between coil-conductor 10, be preferably placed at roundabout component 22 and coil-conductor 10 it
Between adhesive linkage 71 be dielectric constant than other structures beyond the adhesive linkage 71 between roundabout component 22 and coil-conductor 10
The low material of part (protective layer 2 etc.).
Adhesive linkage 72 has insulating properties and adhesiveness, is formed at the substantial entire surface of protective layer 2.Adhesive linkage 72 is for example
It is layer that two-sided adhesion tablet material, bonding agent are constituted etc..In addition, adhesive linkage 72 is not limited to be formed at the substantial of protective layer 2
Entire surface composition, can suitably change.
Roundabout component 21 involved by the embodiment of roundabout component 22 and the 1st of antenna assembly 102 is equally rectangular-shaped
Metal plate.Roundabout component 22 has projection 201 in an interarea (upper surface in Fig. 4 (B)).Projection 201 is, for example, in punching
Flash in acies portion of metal plate etc. is formed at during the punchings such as pressure processing, Laser Processing.
In antenna assembly 102, on roundabout component 22, it is formed with the face of projection 201 (in Fig. 4 (B) in processing
Upper surface) opposite side face (lower surface in Fig. 4 (B)) it is arranged opposite with coil-conductor 10.
It is even this to constitute, the basic composition of antenna assembly 102 also with the antenna assembly involved by the 1st embodiment
101 is identical, also functions to the effect/effect same with antenna assembly 101.
In addition, face and coil-conductor of the antenna assembly 102 due to the opposite side in the face that projection 201 is formed with processing
10 is opposed, therefore, it is possible to prevent the projection 201 of roundabout component 22 from being contacted with coil-conductor 10.Therefore, the contact of projection 201 institute is produced
The problems such as breakage of caused coil-conductor 10, broken string or short circuit, is suppressed.
Moreover, antenna assembly 102 is also equipped with magnetic layer 5.Thus, in the presence of the high permeability of magnetic layer 5, with
The few conductive pattern of the number of turn can obtain given inductance.In addition, according to the collection magnetic effect of magnetic layer 5, it is possible to increase with communication
The magnetic coupling of the antenna of other side side.Moreover, by possessing the composition of magnetic layer 5, can also obtain the magnetic screen effect of rear side
Really.
In addition, in the present embodiment, although show the configuration protection layer 2 between coil-conductor 10 and magnetic layer 5
Configuration example, but magnetic layer 5 can also be configured between protective layer 2 and coil-conductor 10.In addition, coil-conductor 10 can also match somebody with somebody
Put between protective layer 2 and magnetic layer 5.That is, magnetic layer 5 can suitably become relative to the configuration relation of coil-conductor 10
More.But, in the case where antenna assembly 102 is contained in housing, preferably with respect to coil-conductor 10 with being configured with housing
Side it is opposite side configuration magnetic layer 5.According to this composition, because coil-conductor 10 is configured to more lean on than magnetic layer 5
The antenna of nearly communication counterpart side, therefore the coupling raising of antenna assembly 102 and the antenna of communication counterpart side, communication characteristic lifting.
In addition, according to this composition, the Magnetic Shielding Effectiveness of the rear side of magnetic layer 5 can be obtained, can suppress to be configured in housing its
Unnecessary coupling between his part and the grade of antenna assembly 102.

The sectional view of the comparative example of 24A mounting portion.It is simple for ease of understanding accompanying drawing and principle in Fig. 6 (C) and Fig. 7
Change the construction of the roundabout component of diagram.
Roundabout component 24 is different in the point that mounting surface (lower surface in Fig. 6 (B) and Fig. 6 (C)) side is formed with groove 20
In the roundabout component 21 involved by the 1st embodiment.Others are constituted with the antenna assembly 101 involved by the 1st embodiment in fact
It is identical in matter.Hereinafter, the parts different from the antenna assembly 101 involved by the 1st embodiment are illustrated.
In the mounting surface of the roundabout component 24 involved by the 4th embodiment, the 1st connecting portion 31 and the 2nd connecting portion 32 it
Between be formed with two grooves 202.Groove 202 forms the vicinity in the 1st connecting portion 31 and the 2nd connecting portion 32, along roundabout structure
The short side direction of part 24 and formed.The both ends of groove 202 reach roundabout component 24 short side direction (top in Fig. 6 (B) with
And it is following) acies portion.
In the present embodiment, due to being formed with groove 202, therefore energy between the 1st connecting portion 31 and the 2nd connecting portion 32
Enough suppress the moistening of conductive bonding material 61,62 to expand between the 1st connecting portion 31 and the 2nd connecting portion 32.Thus, it is possible to prevent
Conductive bonding material 61 between the 1st connecting portion 31 and coil-conductor 10 and led positioned at the 2nd connecting portion 32 with coil
