Abstract: The foreign matter capture instrument includes: a first manipulation wire; framework wire materials, the base end parts being coupled to a leading end part of the first manipulation wire, and the leading end parts being respectively bundled together; and a second manipulation wire which is coupled to the leading end parts of the framework wire materials, separates from the first manipulation wire extending toward the base end side of the first manipulation wire. By moving the first manipulation wire toward the leading end side relative to the second manipulation wire, the framework wire materials expand and configure a basket, and by further relatively moving the first manipulation wire toward the leading end side, the basket becomes shallower.
