To provide a band for a wiring harness which prevents deflection of a placed plate part on which the wire harness is placed from causing hindrance to fixing the wire harness to a structure, which reduces the weight increase of the placing plate part.

A band for a wiring harness includes: a base member 11, in which cover connecting parts 13 are integrally formed at both ends of a placing plate part 12 on which a wire harness 103 is placed; and a cover plate 21, in which base connecting parts 23, that can be connected to the cover connection parts 13 respectively, are integrally formed at both ends of a presser plate 22 facing the placing plate part 12 so as to be approximately parallel thereto. The wiring harness 103 is bound by respectively connecting the cover connecting parts 13 to the base connecting parts 23, which face each other, with the wiring harness 103 being sandwiched by the placing plate part 12 and the presser plate 22.
