A linear-member-driven manipulator is provided that includes a bendable member that is bendable along a bending plane and includes a plurality of bendable portions; a linear member used to bend at least one of the bendable portions; a plurality of guiding members that guide the linear member that is driven; and a plurality of support members, each support member extending from one of the guiding members to the bendable member, wherein each guiding member is swingable with respect to the bendable member; and wherein, for each support member, a projection distance between the linear member and the support member on the bending plane is greater than or equal to a projection distance between the linear member and a bending neutral line of the bendable member on the bending plane.
