An object is to provide a rotatable connector device that has EMC improved to a required level and thus is usable for multiple high-speed communication. An SRC (10) includes a stator (12) ; a rotator (13) rotatably attached to the stator (12); and a stack-type cable (100) accommodated in an annular accommodation space (S) defined by the stator (12) and the rotator (13). The stack-type cable (100) includes a transmission path FC (101) including a pair of transmission path conductors (130a) and laminate sheets (100a) covering the pair of transmission path conductors (130a) and also includes a dummy FC (102) that is provided on a front surface of the transmission path FC (101) and is formed of laminate sheets (100a) not including a flat rectangular conductor (100b), the transmission path FC (101) and the dummy FC (102) being stacked on each other; the stack-type cable (100) further includes a grease (105) that causes the transmission path FC (101) and the dummy FC (102) stacked on each other to adhere to each other; and a width-direction interval (W) between the pair of transmission path conductors (130a) is set to smaller than, or equivalent to, a conductor width w of each transmission path conductor (130a). |
