To solve the problem of a defect that, in a conventional branch modular connector structure in which a connector body and a cord of a telephone line are disposed on one line, a thickness summing up a telephone line mount plate installed on the wall, the connector body and the telephone cord becomes about 35 mm so that there is a gap between the wall and furniture, and further, even in an existent thin type, cords may become separate and hard to be bundled.

The thickness of a branch connector body is suppressed to 20 mm and a branched cord is curved downward at 90° with respect to a plug, thereby concurrently achieving thinning and easiness in bundling cords.
