Disclosed is an electric junction box capable of preventing an electric wire from entering into a second housing and contacting with an electric wire crimped part, and of allowing a bus bar smoothly to insert into a frame. The electric wire includes a frame and a bus bar. The bus bar includes a plate part, a plurality of terminals projecting in parallel with each other from one end of the plate, and an electric wire crimped part projecting from the other end of the plate. The frame includes a first housing accommodating the plate part and the plurality of terminals, and a second housing projecting from an end of the first housing and accommodating the electric wire crimped part. A tubular peripheral wall composing the second housing includes a slit passing the bus bar therethrough upon the bus bar being inserted into the frame.
