Abstract
When arraying laser-irradiation portions of a plurality of capillaries on the same array plane, simultaneous irradiation of the capillaries with a laser beam incident from the side is enabled by filling the capillaries with a separation medium having a low refractive index of n<1.36 and by setting n=1.00, n=1.46, R/r<5.9, and ΔZ≤9 μm, wherein a distance in a direction perpendicular to the array plane between two capillaries, which are farthest from each other in the perpendicular direction among the capillaries in the laser-irradiation portions, is denoted by 2×ΔZ, wherein an outer radius, an inner radius, a refractive index of an external medium, a refractive index of a material, and a refractive index of an internal medium of each of the capillaries in the laser-irradiation portions are denoted by R, r, n, n, and n, respectively.
