A lift pin of the invention is to be in contact with a substrate having a process-target surface and a non-processed surface, and the lift pin includes: a center member that has a first surface having first surface roughness and including an electrical insulator, and a main body serving as an electroconductive member, and that faces the non-processed surface of the substrate; and a surrounding member that has a second surface having second surface roughness lower than the first surface roughness and including an electrical insulator, that surrounds the periphery of the center member, and that faces the non-processed surface of the substrate.
A lift pin to be in contact with a substrate having a process-target surface and a non-processed surface, the lift pin comprising:
