To provide a container holder adaptable to the size of a container, manufacturable inexpensively with a simple structure, usable both for holding the container storing water and for draining the container, and capable of holding cleanly without having a contact with an outer bottom or a mouth for drinking of the container.

A container holder formed approximately in an α-shape in a plane view is constituted of an annular periphery support part 4, a crossing part 7, a downward hollowed part 5 provided at least on one spot of a substrate 1a and a substrate 1b on both ends and the periphery support part 4, and a handle support part 6 provided on the lower end of the hollowed part 5. Otherwise, the container holder formed approximately in a C-shape in a plane view is constituted of a substrate 1a and a substrate 1b provided on both ends, an opening part, an approximately arc-shaped periphery support part 4, a downward hollowed part 5 provided at least on one spot of the periphery support part 4, and a handle support part 6 provided on the lower end of the hollowed part 5. The substrate 1a and the substrate 1b are connected together with an attachment member 40, and the attachment member 40 is constituted as a strength member of a container holder body, or the substrate 1a and attachment means 20 of the substrate 1b are provided on a washstand or a system kitchen.
