PROBLEM TO BE SOLVED: To provide a buffer for a container in which thickness or bulk of the package is reduced, which has a little possibility of making a space dirty where the container is handled or an adverse effect to the environment, can be reused, and prevent the reduction in impact absorbance. SOLUTION: A precision substrate housing container 10 is housed in a package box 1, and a buffer 20 for releasing the impact on a precision substrate W or the container 10 is interposed between the package box 1 and the container 10. The buffer 20 is composed of a first buffer 23 which is housed at the inside bottom of the package box l to engage with the lower part of the container 10, and a second buffer 24 which is disposed on the package box l to engage with the upper part of the container 10, an external wall 25 and an internal wall 27 forming the first and the second buffer 23 and 24 are connected with a connecting wall 31, and the connecting wall 31 are formed by being bent to form bellows 32 for absorbing the distortion due to the impact.
