To provide a compressor and an oxygen concentration device capable of reducing noise without causing the leakage of noise directly to the outside when raw material air is sucked and compressed air is formed.
The compressor 10 includes a case 23, a drive motor 11 disposed in the case 23 and including an output shaft 15, heads 21, 22 operated by the rotation of the output shaft 15 of the drive motor 11 and sucking and compressing the raw material air 70 to form the compressed air 71, a raw material air intake 90 disposed at the output shaft 15 taking the raw material air 70 in by the rotation of the output shaft 15, and supplying the raw material air to the heads 21, 22 sides, and a filter 95 disposed coaxially with the raw material air intake 90 and removing an impurity in the raw material air by making the raw material air 70 pass through the filter.
