The present invention addresses the problem of providing a white blood cell capturing device that captures white blood cells with high efficiency while being unsusceptible to capturing other material. The problem is solved by this white blood cell capturing device, which captures white blood cells included in a blood-containing liquid, and includes a sample entrance, a buffer entrance, a white blood cell separation unit, a main part, an auxiliary part, and an exit, wherein: the main part has a flat portion and a large number of protrusions provided thereon, the main part being configured such that a buffer which has entered from the entrance passes above the main part and is discharged from the exit; the protrusions are provided in layered form on the surface of the flat portion, each layer includes a plurality of the protrusions, and the protrusions are configured such that a buffer that has passed through a layer on the entrance side passes through a layer on the exit side adjacent thereto; and the capture part faces the exit side of all or some of the bypass parts in a specific layer, and is disposed as a part of a separate layer adjacent thereto.
