An electrical junction box having a first casing superimposed on a second casing, the first casing being fitted in a peripheral wall portion of the second casing to form an electrical junction box body, said electrical junction box comprising:

• an engagement lock portion provided on an outer surface of the peripheral wall portion of the second casing;
• and
• a bracket attached to said engagement lock portion from a side of an opening defined by the peripheral wall portion;
• wherein a fitting projection portion extends from a bottom wall section of the first casing to an outer peripheral surface adjacent said engagement lock portion;
• and
• said bracket is provided with a fitting recess in which said fitting projection portion is fitted during coupling of said bracket to said engagement lock portion in order to restrain said bracket from moving outward from said first casing;
• wherein said engagement lock portion includes two adjacent engagement lock parts spaced laterally on the outer surface of the peripheral wall portion of the second casing, and said fitting projection portion is disposed on a portion corresponding to between said two engagement lock parts;
• wherein said fitting projection portion includes a narrow width leg portion and a wide width head portion at an end of said leg portion, said wide width head portion extending in a fitting direction of said fitting recess of said bracket, and said narrow width leg portion extending from an outer peripheral corner portion of the bottom wall section of the first casing to a bottom surface of the bottom wall section.
