Abstract: The present disclosure has an object of providing a power supply block suitable to be shared among different types or classes of vehicles. A power supply block includes a block main body including a first insertion port for inserting a power supply terminal and a first fuse terminal insertion port for inserting a connection terminal, a conductive first conduction member that is held inside the block main body and configured to be electrically connected to the power supply terminal, and a conductive second conduction member that is held inside the block main body, is electrically connected to the first conduction member inside the block main body, and is configured to be electrically connected to the connection terminal.

Abstract: The present disclosure provides a routing member and a wire harness that are capable of absorbing tolerances. A wire harness 10 has a routing member 40. The routing member 40 has a body portion 41 having a columnar shape, and a groove portion 42 in which a wire 20 is to be accommodated, the groove portion 42 being formed on an outer circumferential side of the body portion 41. The groove portion 42 has a meandering portion 45 extending in an axial direction of the body portion 41 while meandering. The wire harness 10 has the wire 20 accommodated in the groove portion 42 of the routing member 40 and routed along the groove portion 42.

Abstract: A circuit apparatus includes: a stacked body; and a plurality of terminals. The stacked body includes a plurality of layers. A plurality of holes that extend through the plurality of layers are formed in the stacked body. Each of the plurality of layers includes a connection member that is formed of a conductor. The connection member includes: a plurality of connection portions that are provided at positions corresponding to the plurality of holes; and a joining portion that connects the plurality of connection portions to each other. The plurality of terminals include a plurality of types of terminals that correspond to the plurality of layers. Each of the plurality of types of terminals can be selectively connected to the connection portion of a corresponding one of the plurality of layers by being inserted into a predetermined one of the plurality of holes.
