In the present invention, the housing is arranged such that part or all of the tip of the radiating element of the antenna extends on the surface (inner surface) facing the columnar member (side end) in the outer fitting portion of the housing. An inlet may be arranged with respect to the body. 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 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 antenna and the metal columnar member by electromagnetic induction or electrostatic induction, and the columnar member serves as a part of the antenna, that is, as an extension portion extending the antenna. Function. 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.

 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. 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 protruding direction of the columnar member with respect to the housing is on both ends in the width direction of the housing. In this way, the directivity of the antenna can be made wider (directivity) through the metal columnar member than when the columnar member protrudes from the housing only on one end side in the width direction of the housing. 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.
The coating is provided for the purpose of protecting the inlet, improving the adhesion between the outer fitting portion and the columnar member, and improving the holding force of the outer fitting portion with respect to the columnar member.
The thickness of the coating is appropriately adjusted according to the purpose.

 The material for forming this film is not particularly limited, but for the purpose of improving the adhesion between the outer fitting portion and the columnar member, or the holding force of the outer fitting portion with respect to the columnar member, acrylic rubber, acrylonitrile butadiene rubber, A synthetic rubber (elastic rubber) selected from isoprene rubber, urethane rubber, ethylene propylene rubber, epichlorohydrin rubber, chloroprene rubber, silicone rubber, styrene butadiene rubber, butadiene rubber, fluorine rubber, butyl rubber, and the like is preferably used.
