<p>The purpose of the present invention is to affix a relay block to a compact to enable an on-vehicle electrical connection box to be reduced in size. A relay block (11) configures an on-vehicle electrical connection box, and is provided with: relay placement parts (13); and terminal insertion holes (14) which downwardly extend from bottom surfaces of the relay placement parts (13), and into which relay terminals are inserted. A plurality of the terminal insertion holes (14) are arranged so as to enable the insertion of relay terminals, i.e. a terminal arrangement provided with two terminal groups comprising a plurality of terminals which are arranged in parallel and have an arrangement direction orthogonal with respect to each other, said terminal arrangement also being provided with a narrowed portion which is narrower than other portions and which has, omitted therefrom, one portion having a square-shaped outline when viewing a terminal-equipped portion in a planar view. A recess (15) extending further inside than other portions is formed at an outer-side surface of a narrowed-portion-corresponding portion of the terminal insertion holes (14). A connection engagement part (16) for connecting relay blocks (11) to each other is formed in this recess (15) to reduce length when connected.</p> |
