<P>PROBLEM TO BE SOLVED: To easily control the start and stop of power feed to an electronic apparatus through a communication cable. Ž<P>SOLUTION: This electronic apparatus 2 includes a power control part 20 having a detection resistor 231 and receiving power feed from a power feed device 1 through a communication cable 3, wherein the power feed is started by detecting the detection resistor 231 through the communication cable 3 by the power feed device 1, and stopped by carrying a current above a threshold value to the communication cable 3. In the electronic apparatus 2, the power control part 20 includes: a power supply means 230 to supply power by receiving the power feed; a connection control means 220 to electrically connect the communication cable 3 to the detection resistor 231 when receiving an operation for starting the power feed, and keep the electrical connection by the power supplied from the power supply means 230; and a cutoff control means 240 to carry the current above the threshold value to the communication cable 3 by the power supplied from the power supply means 230 based on a predetermined condition.
