Fluidic device, transfer member, and method for fabricating fluidic device

A fluidic device, comprising:

• a porous flow path member;
• an absorbent member in contact with the flow path member and configured to absorb a liquid, wherein the absorbent member does not comprise a fiber material;
• and
• a barrier member disposed over and covering at least a portion of the absorbent member and being in contact with a flow path wall of the porous flow path member,
• wherein the barrier member is a film or a laminate that has a water gas permeability of 100 g/(m2·day) or less, and wherein a thickness of the barrier member is from 5 μm to 100 μm,
• wherein the absorbent member comprises a liquid-absorbent polymer that absorbs the liquid, and a lyophilic polymer having lyophilicity to the liquid, wherein liquid-absorbent polymer is conjugated by the lyophilic polymer in the absorbent member such that voids are formed in the absorbent member, wherein a voidage in the absorbent member is from 30% to 85%, and wherein a ratio of the lyophilic polymer in the absorbent member is from 1% to 60% by mass, and
• wherein the fluidic device does not comprise a housing.
