[Problem] To provide a sterile connecting apparatus with lower weight and size to facilitate cost reduction. [Solution] A sterile connecting apparatus (1) including: a motor (500) having a driving gear (611) on an output shaft; a control unit (100) which instructs driving of the motor; a movable clamp unit (72) which holds a first tube (T1) and a second tube (T2) in a stacked manner; a heating plate member moving unit (651) which moves a heating plate member, which is a wafer (WF), between a standby position (PS1) and a melt position (PS2) according to rotation of the driving gear (611) of the motor in order to melt and cut the first tube and second tube, the standby position (PS1) being a position away from the first and second tubes, and the melt position (PS2) being a position where the first and second tubes are to be melted and cut; and a rotation manipulation unit (610) which rotates the movable clamp unit (72) while the heating plate member is at the melt position (PS2) according to rotation of the driving gear of the motor so that the melted/cut end portion of the first tube and the melted/cut end portion of the second tube are swapped with each other.
