<p><P>PROBLEM TO BE SOLVED: To provide a capsule medical instrument generating a power by a power receiving coil without lowering a transmission efficiency of energy to be fed from outside the body, reducing a packaging space of internal components and miniaturizing the size. <P>SOLUTION: A rectangular flexible board 24, on its one surface, is formed with a plurality of power receiving coil wires 25a, folded into an approximately square cylindrical shape, and soldered in its ends 25b in the opposed two sides to form a coil connecting part 28. A spiral power receiving coil 25 is thus formed and its outer circumferential side is covered with an external member 23 formed of resin and the like. The power receiving coil 25 is formed of a thin film into a size close to the outer diameter of the external member 23 for the space saving, thereby efficiently generating the power in a small size. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
