1. A non-contact communication medium comprising:
- a conductive loop antenna formed on one side of a circuit board; and
a communication circuit mounted on the one side of the circuit board, wherein one end of the loop antenna is connected to one antenna connection part of the communication circuit, and wherein an arm part provided with a first pad part, a second pad part, and a conducting part for allowing conduction between the first pad part and the second pad part is collapsibly provided such that, when the arm part is collapsed, the other end of the loop antenna contacts the first pad part and the other antenna connection part of the communication circuit contacts the second pad part.

Abstract
A loop antenna is formed on one side of a circuit board and an IC chip is mounted on the same side of the circuit board. An inner end of the loop antenna is connected to an antenna connection terminal of the IC chip. An arm part provided with a first pad part, a second pad part, and a conducting wire for allowing conduction between the fist pad part and the second pad part is collapsibly provided in such a manner that, when the arm part is collapsed, an outer end of the loop antenna contacts the first pad part and an antenna connection terminal of the IC chip contacts the second pad part.

10. A non-contact communication medium comprising:
-
a circuit board;
a conductive loop antenna formed on the circuit board;
an arm part that is removable from the circuit board by a removal hole such that one end of a part of the circuit board is remaining, the arm part being collapsible by the remaining one end functioning as a folding part;
a communication circuit mounted on the arm part;
a first pad part formed on the same side of the circuit board as the side on which the communication circuit of the arm part is mounted;
a second pad part formed on the same side of the circuit board as the side on which the communication circuit of the arm part is mounted, such that the second pad part is connected to a second antenna connection part;
a conducting part for allowing conduction between a first antenna connection part and the first pad part;
a third pad part formed at an end of the circuit board located outside the loop antenna; and
a fourth pad part formed at an end of the circuit board located inside the loop antenna, wherein the arm part is provided such that, when the arm part is collapsed, the first pad part contacts the third pad part and the second pad part contacts the fourth pad part. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
