The outer wall has a plate-shaped protruded portion, and the protruded portion has a pair of side portions respectively placed at one end and the other end in a width direction. The side wall has a pair of edge portions and has a notch between the pair of edge portions. Each of the pair of edge portions has a first facing surface and a second facing surface. The first facing surface abuts on the pair of side portions in a thickness direction of the protruded portion, and the second facing surface faces the pair of side portions in the width direction and positions the cover with respect to the frame. ## Claims ### Claim 1 An electric connection box comprising: a frame having a cylindrical outer wall and having a housing space on an inner side of the
