A living body tissue closing device 1 includes an elongated body element 2, a clip (living body tissue closure) 4 for closing a wound hole which penetrates a living body tissue membrane, and a thread 8. The body element 2 includes a sheath 5, and elongated feeding and deformation means 3. The elongated feeding and deformation means 3 includes a covered tube 6, a pusher tube 7, a thread anchoring cap 9, a guide wire 11, and a stopper 12. The clip 4 includes a seal portion 41 for covering the wound hole and a peripheral portion of the wound hole from one side of the living body tissue membrane, a deformation portion 42 deformable between a first form in which the deformation portion 42 can pass through the wound hole and a second form in which the deformation portion 42 can cooperate with the seal portion 41 to sandwich the living body tissue membrane therebetween from the other side, and a fastener portion 43 for retaining the deformation portion 42 in the second form.
