A noise absorber capable of preventing a cable from becoming damaged with a high degree of reliability while demonstrating outstanding noise absorbing characteristics is provided with a cover 1 and a pair of ferrites 21 and 22. The cover 1 is constituted through the combination of a first cover 11 and a second cover 12. The first cover 11 is provided with a ferrite storage portion 110 and a cable storage portion 111. The second cover 12 is provided with a ferrite storage portion 120 and a cable storage portion 121. The ferrite storage portion 110 is formed at an internal surface of the first cover 11 and the ferrite storage portion 120 is formed at an internal surface of the second cover 12. The cable storage portion 111 is formed adjacent to the ferrite storage portion 110 at a side thereof, whereas the cable storage portion 121 is formed adjacent to the ferrite storage portion 120 at a side thereof. The pair of ferrites 21 and 22 are provided in the ferrite storage portions 110 and 120 at the first cover 11 and the second cover 12 respectively and are combined so as to form between them a cable passage constituted of indented grooves 211 and 222. The indented grooves 211 and 222 and the cable storage portions 111 and 121 constitute a continuous cable guide passage.
