PROBLEM TO BE SOLVED: To generate the driving power by the conventional transmission power and to achieve energy-saving of a wireless feeding system and miniaturization of a capsule endoscope by improving the receiving efficiency of the wireless power feeding system applicable to the capsule endoscope without any increase in size of the capsule endoscope itself. SOLUTION: This feeding system 2 includes a feeding antenna 5 for transmitting power from a power supply 6 by wireless, wherein the system includes a receiving antenna 12 for receiving the transmitted power, which is formed by winding a receiving coil 12b around the outer periphery of a substantially bar-like core 12a, and at least one end area of the core of the receiving antenna is tilted at a predetermined angle to the linear area.
