1. A service plug having a service plug body that is attachable to and detachable from a power feed circuit unit provided with a first power feed circuit that electrically interconnects a high-voltage battery and a drive device to which power is supplied from the high-voltage battery, the service plug body being attached to the power feed circuit unit to close the first power feed circuit, the service plug body comprising:
a pair of first conductive members configured to be electrically connected to a pair of first connection terminals provided in the first power feed circuit, such that when the service plug body is attached to the power feed circuit unit, the pair of first conductive members become electrically connected to the pair of first connection terminals to close the first power feed circuit; and
a pair of second conductive members configured to be electrically connected to a pair of second connection terminals provided in a second power feed circuit that electrically interconnects an auxiliary battery and an auxiliary load to which power is supplied from the auxiliary battery, such that when the service plug body is attached to the power feed circuit unit, the pair of second conductive members become electrically connected to the pair of second connection terminals to close the second power feed circuit after the pair of first conductive members become electrically connected to the pair of first connection terminals.
