A back side substrate support portionincludes a lower side inclined faceon which an end of a back face of a substrate W slides, and a substrate support portionthat is located above the lower side inclined faceand can support an edge portion of the substrate W. When a container main body opening portionis closed by a lid body, the edge portion of the substrate W slides on the lower side inclined faceand reaches the substrate support portion. At least a portion of the lower side inclined faceis configured from a second member that is different from a first member that configures the substrate support portion, and the second member has a lower maximum static friction coefficient and lower wear resistance than the first member.
