Abstract
A particle capture device includes first and second substrates. The first substrate has recessed portions that have a size capable of capturing one particle. Each recessed portion has connection holes that have a size capable of allowing a dispersion medium of particles to move therethrough. A flow path that has the connection holes as an inlet port and an end portion of a first side of the first substrate as an outlet port is defined between the first substrate and the second substrate. A total opening area of the connection holes is 1 mmor more and less than 10 mm, and a cross-sectional area of the flow path at the outlet port is 0.8 times or more the total opening area; or the total opening area is 10 mmor more and 1000 mmor less, and the cross-sectional area is 0.1 times or more the total opening area.
