A charging period during which the secondary battery is charged based on the received power and a non-charging period are set in a time-divisional manner. The state notification section notifies of the unit state based on the received power in both of the charging period and the non-charging period. ## Claims ### Claim 1 An electronic unit, comprising: an electricity reception section configured to receive a power transmitted via one of a magnetic field or an electric field; a charging section configured to store the power; wherein a charging period and a communication period are set in a time-divisional manner; and a state notification section configured to: notify information of the electronic unit to an outside environment of the electronic unit; and notify, in the communication period, the information of the electronic unit based on the stored power in the charging section. ### Claim 2 (depends on 1) The electronic unit according to claim 1, wherein the state notification section includes: a lighting section configured to notify the information based on a lighting state; and a lighting control section configured to control the lighting state of the lighting section based on the received power. ### Claim 3 (depends on 2) The electronic unit according to claim 2, further comprising: a control section configured to control the lighting state based on the stored power in the charging section in the communication period. ### Claim 4 (depends on 3) The electronic unit according to claim 3, wherein the control section is further configured to control the lighting state based on the stored power in an overlapping period with the charging period, and the overlapping period is before and after the communication period. ### Claim 5 (depends on 1) The electronic unit according to claim 1, wherein the communication period is a period in which the electronic unit is configured to communicate with a power feeding unit that transmits the power. ### Claim 6 (depends on 5) The electronic unit according to claim 5, wherein, in the communication period, supply of the received power is stopped to each of the charging section, the state notification section, and a load located in a downstream of the charging section and the state notification section. ### Claim 7 (depends on 1) The electronic unit according to claim 1, wherein the charging period is a period in which the charging section is configured to charge a secondary battery. ### Claim 8 (depends on 1) The electronic unit according to claim 1, wherein the communication period is continuously set based on a completion of the power storage in the charging section. ### Claim 9 (depends on 8) The electronic unit according to claim 8, wherein the communication period is set at a first frequency, based on the completion of the power storage in the charging section, wherein the communication period is set at a second frequency, during the power storage in the charging section, and wherein the first frequency is lower than the second frequency. ### Claim 10 (depends on 1) The electronic unit according to claim 1, wherein the state notification section is further configured to separately notify first information of the electronic unit during the power storage of the charging section and second information of the electronic unit that indicates a completion of the power storage in the charging section. ### Claim 11 (depends on 1) The electronic unit according to claim 1, wherein in the communication period, the state notification section is further configured to notify the information of the electronic unit based on a part of the received power. ### Claim 12 A power feeding system, comprising: at least one electronic unit; and a power feeding unit configured to transmit a power to the at least one electronic circuit via one of a magnetic field or an electric field, wherein each electronic unit of the at least one electronic unit includes: an electricity reception section configured to receive a power transmitted via one of the magnetic field or the electric field; a charging section configured to store the power; wherein a charging period and a communication period are set in a time-divisional manner; and a state notification section configured to: notify information of the electronic unit to an outside environment of the electronic unit; and notify, in the communication period, the information of the electronic unit based on the stored power in the charging section.
