1. An electrical junction box comprising:
a housing having a bus bar placement surface and a through hole, wherein the through hole has a first end side and a second end side opposite to the first end side in an axis direction of the through hole and the first end side is opened in the bus bar placement surface;
a bus bar having a plate shape and having a first bolt hole that has a hole diameter smaller than a hole diameter of the through hole, the bus bar configured to be placed on the bus bar placement surface and configured to be fixed to the housing such that the first bolt hole and the through hole communicate with each other;
a nut configured to be inserted from an opening of the second end side of the through hole and configured to be accommodated in the through hole; and
a cap having insulating properties and configured to be attached to the housing to close the opening of the second end side of the through hole,
wherein a terminal having a plate shape and having a second bolt hole is fixed to the bus bar by fastening a bolt inserted into the second bolt hole and the first bolt hole in this order to the nut so as to sandwich the bus bar and the terminal that is disposed so as to overlap the bus bar,
wherein the housing includes a tubular portion defining the through hole,
wherein the cap includes a lid portion configured to close the opening of the second end side of the through hole, and a protruding portion protruding from the lid portion toward the first end side of the through hole along an outer peripheral surface of the tubular portion, and
wherein the protruding portion and the outer peripheral surface of the tubular portion constitute a locking mechanism preventing the cap from being separated from the housing.
