That is, when the outer fitting portion of the housing is fitted between two adjacent columnar members, the housing is arranged such that a part or all of the distal end portion of the radiating element is interposed between the columnar member and the outer fitting portion. An inlet may be arranged with respect to the body. In this way, when the columnar member is made of metal, a current flows between the radiating element of the antenna and the metal columnar member by electromagnetic induction or electrostatic induction, and the columnar member is a part of the antenna. Part, that is, functions as an extension part obtained by extending the antenna. Therefore, communication with the antenna alone is not possible from the longitudinal direction of the inlet, but communication is also possible from the longitudinal direction of the inlet via the columnar member that forms the extension of the antenna. That is, the antenna directivity can be widened (directivity weakened) through the metal columnar member.

The columnar member protrudes from the casing when the columnar member is partially or entirely crossed with the tip of the radiating element of the antenna. It is larger than the length in the direction perpendicular to the longitudinal direction of the housing. If it does in this way, transmission / reception of a radio wave can be performed more efficiently also from the longitudinal direction of an inlet via a metal columnar member. That is, the directivity of the antenna can be made wider (directivity weaker) through the metal columnar member.

Furthermore, it is preferable that the direction which protrudes with respect to the housing | casing of a columnar member is the both ends side of the width direction of a housing | casing. In this way, the directivity of the antenna can be made wider via the metal columnar member than when the columnar member protrudes with respect to the casing only on one end side in the width direction of the casing ( Directivity can be weakened).
In addition, the protrusion amount with respect to the housing | casing of a columnar member is not specifically limited, It adjusts suitably as needed.

Further, in order to generate electromagnetic induction or electrostatic induction between the tip of the radiating element of the antenna and the columnar member, they may or may not be in close contact with each other. All you need is it. Therefore, a coating may be provided on one surface of the inlet so as to cover the antenna and the IC chip.

In addition, although this embodiment illustrated the case where the inlet 140 which has the 1st antenna 142 which consists of a dipole antenna comprised from a pair of planar radiation elements 145 and 145 was provided, this invention is limited to this. It is not a thing. In the present invention, the first antenna may be a dipole antenna composed of a pair of frame-shaped radiating elements, a meander-shaped dipole antenna, a monopole antenna, or the like. It may be an antenna.
In the present embodiment, the case where the second antenna 151 of the antenna member 150 is disposed in the one surface 131a of the connecting portion 131 of the housing 130 is illustrated, but the present invention is not limited to this. In the present invention, a part or all of the tip of the radiating element of the second antenna extends on the surface (inner surface) facing the columnar member (side end) in the outer fitting portion of the housing. An antenna member may be disposed with respect to the housing. That is, when the outer fitting portion of the housing is fitted between two adjacent columnar members, the housing is arranged such that a part or all of the distal end portion of the radiating element is interposed between the columnar member and the outer fitting portion. An antenna member may be arranged with respect to the body.

In particular, when the columnar member is made of metal, it is preferable that a part or all of the tip of the radiating element is arranged so as to intersect the columnar member. In this case, the angle at which a part or all of the tip of the radiating element intersects the columnar member is preferably 90 °, and practically 45 ° to 90 °.
As a result, a current flows between the radiating element of the second antenna and the metal columnar member by electromagnetic induction or electrostatic induction, and the columnar member is a part of the second antenna, that is, the second antenna. It functions as an extended part. Therefore, although only the second antenna cannot communicate from the longitudinal direction of the antenna member, it can communicate from the longitudinal direction of the antenna member via the columnar member that forms an extension of the second antenna. That is, the directivity of the second antenna can be widened (directivity is weakened) via the metal columnar member.

 In addition, when the columnar member is made of metal and the outer fitting portion of the housing is fitted to two adjacent columnar members, one surface of the housing or the other surface (on the side opposite to the one surface) It is preferable that the columnar member protrudes from the housing as viewed from the surface. If it does in this way, transmission / reception of a radio wave can be performed more efficiently also from the longitudinal direction of an antenna member via a metal columnar member. That is, the directivity of the second antenna can be made wider (directivity weaker) through the metal columnar member.

Furthermore, it is preferable that the direction which protrudes with respect to the housing | casing of a columnar member is the both ends side of the width direction of a housing | casing. In this way, the directivity of the second antenna can be made wider via the metal columnar member than when the columnar member protrudes from the casing only on one end side in the width direction of the casing ( Directivity can be weakened).
In addition, the protrusion amount with respect to the housing | casing of a columnar member is not specifically limited, It adjusts suitably as needed.

 Moreover, in order to generate electromagnetic induction or electrostatic induction between the tip of the radiating element of the second antenna and the columnar member, both may or may not be in close contact with each other. All you have to do is Therefore, a film may be provided on one surface of the antenna member so as to cover the second antenna.
