摘要：
A contact detection instrument 1 is provided with a rod 12, a tip sensor portion 20 that is attached to one end of the rod 12 and is inserted into a living body through a hole, a speaker 14 that, from outside the living body, inputs a sound into a hollow space that is formed in the interior of the rod 12 and the tip sensor portion 20, and a microphone 15 that, outside the living body, outputs an electrical signal that corresponds to the sound inside the hollow space, with the tip sensor portion 20 including an elastic material that covers the hollow space.
