- the method is not limited as long as the antenna and the jumper wire are physically or electrically connected.
- the antenna 61 is formed with a connection portion 64 for connection with the IC module. It is desirable that the connection portion has a large area because it can be easily connected to the IC module.
- the shape of the antenna may be formed in a shape corresponding to the communication characteristics used by the non-contact communication medium. Depending on the type of antenna, a jumper wire may be formed on the surface of the antenna sheet, or a jumper wire is unnecessary. In some cases, the shape is not limited to that shown in FIG.
- the antenna 61 and the jumper wire 62 are formed by forming aluminum, copper, silver or the like on the surface of the antenna sheet into a thin film having a thickness of about 0.02 mm to 0.05 mm, and patterning the thin film by etching or the like.

This is because stress is prevented from concentrating on.
- the antenna in the present invention is not limited to the etching antenna, and a wound coil made of a conductive wire, an antenna provided with conductive ink by printing, or the like can be used.
- a hole 65 for accommodating the IC module is provided in the antenna sheet. This further reduces the thickness and thickness of the non-contact communication medium, prevents local stress from acting, and improves resistance to bending. Further, the IC module can be fixed by accommodating up to the lead frame of the IC module in the hole. In addition, if the connection portion 64 is formed by increasing the area of the portion connected to the IC module of the antenna, the connection is easy.

- the connection portion of the antenna can be connected over the entire width in the width direction of the terminal portion of the IC module, and the connection can be made reliably, and the reliability of the antenna and the inlet can be improved.
- the length of the antenna connection portion 64 is larger than the length of the portion where the terminal portion of the IC module and the antenna connection portion overlap.
- the edge of a terminal part is connected so that it may be located in the approximate center part inside an edge part of the connection part of an antenna. For this reason, the edge of a terminal part contact

- the connection part of an antenna can be supported and reinforced by both the 2nd board
- the edge of the terminal portion can be received by the substantially central portion of the antenna connection portion whose width is increased. . Thereby, concentration of stress on the antenna can be prevented, and disconnection of the antenna can be prevented.

- the hole may be a recess.
- the sealing material When the sealing material is bonded so as to extend not only to the mold part as shown in FIGS. 4 (a) and 4 (b) but also to part of the antenna sheet, the bonding strength between the IC module and the antenna sheet increases, In particular, the CD direction is desirable because the bonding strength between the IC module and the antenna connection portion is increased.
- the MD direction since the sealing material covers a wide area, the MD direction is used when a linear pressure test is performed in the CD direction. In addition, when a linear pressure test is performed in the MD direction, stress is easily applied to the mold part in the CD direction, which causes cracks.
- FIGS. 5A and 5B and FIGS. 6A and 6B at least one of the MD direction and the CD direction is set so that the sealing material does not contact the antenna sheet. It is desirable.
- FIG. 5 it is the structure by which the edge part of the sealing material is arrange
- FIG. 5 it is the structure by which the edge part of the sealing material is arrange
- a sealing material may contact an antenna sheet. Absent.
- the horizontal width (CD direction) of the sealing material is x
- the vertical width (MD direction) is y
- the horizontal width of the hole of the second base material is a
- the vertical width is b (see FIG. 7).
- the above conditions (1) and (2) are that the sealing material is pressed against both side surfaces of the mold part 42 by the inner side surface of the opening of the first base material, and is adhered to both side surfaces of the mold part. Is taken into account. If these conditions are satisfied, the part of the sealing material that is not pressed down by the inner surface of the opening of the first base material will naturally hang, or if it adheres to the side surface of the mold part by some means, It does not contact the antenna sheet, and does not contact the antenna sheet even if it is configured to spread straight in the horizontal direction (see FIG. 6).
- the sealing material 5 that satisfies at least one of the formulas (1) and (2) it is possible to prevent the antenna sheet from being reliably contacted in at least one of the MD direction and the CD direction.
- a linear pressure test it is possible to prevent stress from being applied to the mold part 42 and causing cracks.
- (1) and (2) may satisfy at least one of the conditions, but it is more desirable to satisfy only the condition (2).
- a sealing material is formed so as to cover the connecting portion in the CD direction in which the IC module 4 and the antenna are connected, and the sealing material is bonded to the second base material (antenna sheet) 31 in the MD direction orthogonal to the MD direction. It is because it becomes the structure which does not. This is because the CD direction is the long side direction of the die pad 431, and the terminal portion is formed so as to protrude from the mold portion 42. Since the terminal portion is connected to the antenna connection portion 64 here, it is covered with the sealing material 5. This is because it is preferable to give priority to reliably preventing static electricity from entering.

端子部は、例えば、金(Au)等のボンディングワイヤ44を介してICチップの入出力パッド(図示せず)に接続されている。
図5では、第一の基材の開口部とモールド部の側面の間で封止材の端部が配置された構成であり、第一の基材の開口部をモールド部の径に一致させることで、第一の基材貼り合わせ時に第一の基材の開口部の内側面により押さえつけられ、モールド部側面に封止材が接着され、封止材の端部が固定される。また図6では、モジュール径に対して第二の基材の孔部の幅が、封止材の端部が基材に接触しない程度に大きいので、封止材がアンテナシートに接触することがない。
このためには、封止材の横幅(CD方向)をx、縦幅(MD方向)をyとし、該第二の基材の孔部の横幅をa、縦幅をbとし(図7参照)、該第一の基材の厚さをdとして、
