PROBLEM TO BE SOLVED: To provide a metal bumper resin spacer capable of using a sensor attached to a whichever bumper, a resin bumper or a metal bumper, and capable of preventing a detection error resulting from the reflection of vibration in the metal bumper, and to provide an attachment structure of a sensor to a bumper using the metal bumper resin spacer.SOLUTION: A sensor attachment structure includes: a resin spacer 3 that is closely arranged on at least opening circumferential portion 10K of a bumper opening 10h of a metal bumper main body 10 from a bumper back surface 10b; and a sensor 200. The sensor 200 includes: a front-surface-side abutment portion 21c abutting on the opening circumferential portion 10K from a bumper front surface 10a; an opening insertion portion 22B inserted into the bumper opening 10h; and a resin back-surface-side abutment portion 22A abutting on a back surface 3b of the spacer 3 that is on a back side of the opening circumferential portion 10K. The spacer 3 is formed of a softer material than at least the back-surface-side abutment portion 22A. |
