A high-frequency snare for an endoscope includes an electrically insulating sheath, an operation wire slidably inserted through the sheath, a plurality of resilient twisted wires. Proximal ends of the plurality of twisted wires are connected to the distal end of the operation wire. Distal ends of the plurality of twisted wires are deposited with each other within an atmosphere of inactive gas. A proximal end side of the deposited ends of the plurality of wires being connected together with a metallic connecting member. When the operation wire is operated to withdraw at least proximal side portions of the plurality of twisted wires, the twisted wires are tucked. The plurality of twisted wires are expanded to form a loop with resilience thereof when the plurality of twisted wires are protruded from the sheath.
