Kitchen knife holder and kitchen knife holder unit

A kitchen knife holder has a configuration including: a holder body for suspending a kitchen knife entirely by holding a top of a spine of the kitchen knife; and a magnet array attached to the holder body. The holder body includes two or more magnets spaced at an interval and arranged in an array pattern, and used for magnetically supporting the top of the spine of the kitchen knife in a manner allowing the top to be attached and detached freely. The magnet array is arranged at a substantially center position of the holder body in a width direction as viewed from one end of the holder body.
