Abstract: There is provided an electrical junction box which can improve rigidity of a case body. An electrical junction box includes a block, a case body and an inner cover which regulates a wiring path of an electric wire attached to the block. The case body is formed into a deep box-like shape having a peripheral wall, a bottom wall and an opening portion, wherein a portion of the case body adjacent to the bottom wall has a tapered shape. Cutout portions are formed at two opposing faces of the peripheral wall. A width of the cutout portion is smaller when the case body is in a natural condition in which the block is not housed in the case body than when the block is housed in the case body. The width of the cutout portion is broadened as the block is inserted into the case body.
