Electrical connection box with dark current circuit connection/disconnection structure

An electrical connection box having a dark current circuit connection/disconnection structure includes a case for housing a dark current circuit, and a conduction member holder for holding a conduction member for conductively connecting the dark current circuit, the conduction member holder being attached to the case and movable in an insertion and removal direction of the conduction member, the conductive member being held in a manner that allows switching between a connection position conductively connected to a connection terminal of the dark current circuit housed in a cavity of the case and a disconnection position disconnected from the connection terminal,

• wherein, the conduction member holder includes a conduction member holding portion that extends spanning over a plurality of cavities provided in the case,
• the conduction member includes a first conduction member configured to be connected to the connection terminal of the dark current circuit that is housed in one of the cavities, and a second conduction member configured to be simultaneously connected to the connection terminal of the dark current circuit housed in one of the cavities and a connection terminal of another circuit that is housed in another one of the cavities, and
• the first conduction member or the second conduction member is selectively mounted in the conduction member holding portion according to a required circuit configuration.
