A terminal (20) includes a connecting portion (24) to which a plurality of wires (11, 12) including conductors (13, 14) having different thicknesses are to be connected side by side, and the connecting portion (24) is stepped. A terminal-wire assembly (10) includes a plurality of wires (11, 12) including conductors (13, 14) having different thicknesses and a terminal (20) including a connecting portion (24) to which the plurality of wires (11, 12) are to be connected side by side, and the connecting portion (24) is stepped. In the terminal-wire assembly (10), the wire (12) connected at a high position on the connecting portion (24) includes the thinner conductor (14) than the wire (11) connected at a low position on the connecting portion (24).
