PURPOSE: To obtain a test carrier wherein a two-process reaction cycle is possible, uniform wetting of a detection layer itself is reliable even if an extremely small quantity of sample and an extremely thin layer are provided and uniform coloring is reliable, by including a separation layer having functions for separating and distributing to fluid simultaneously. CONSTITUTION: A separation layer 12 is constituted wherein it is placed in a fluid transfer path after a reserving layer 4 between detection layers 11 and 4 for forming a detectable signal, so that fluid contact is caused only by a pressure load pressed against an opposite side. The layer 12 comprises a hydrophilic material and has a lattice structure, wherein an average width of a lattice opening is larger than 0.05mm, and a thread of the lattice structure is formed of multi-filament. This constitution enables a twoprocess reaction cycle, allows the layer 11 itself to be wetted uniformly even with an extremely small quantity of sample and an extremely thin layer, and enables uniform coloring.
