The invention provides a rotary connector of lower cost. After a lead block (1), where a required number of pin terminals (3) are fitted to and assembled with an insulating support member (2), is connected to an end portion of a flat cable (20), the lead block (1) is assembled with a lower connector holder (12a) of a rotary connector (30). The lower connector holder (12a) includes lower protruding portions (17a, 18a) of a lower cover (18) and an outer cylindrical portion (17) that are snap-fitted to each other. The lower protruding portion (17a) includes a receiving recess (17b) and the lower protruding portion (18a) includes a holding wall portion (18b). Leading end portions (3a) of pin terminals (3) are inserted into insertion holes (18d) of the holding wall portion (18b), so that the lead block (1) is assembled. While stopper portions (3e) of the pin terminals (3) are interposed between the holding wall portion (18b) and the outer wall (2g) of the support member (2), the support member (2) is positioned and held in the receiving recess (17b).
