A connector for a board and an electrical junction box that utilizes the connector are provided. The connector prevents adjacent terminal metals from causing a short circuit. Each connector housing includes a hood section having an inner wall. Protrusions are provided on an outer surface of each inner wall to project outward in a thickness direction of the inner wall. Openings around adjacent through-holes are shifted in the thickness direction of the inner wall. Thus, it is possible to increase a distance on surface between adjacent terminal metals inserted into the adjacent through-holes. The distance on the surface between adjacent terminal metals prevents water adhering to the terminals metals from short-circuiting the adjacent terminal metals.
