PROBLEM TO BE SOLVED: To provide a flow resistance reduction structure and a flow resistance reduction method capable of reducing flow resistance of main flow liquid, with a simple structure. SOLUTION: This flow resistance reduction structure 10 includes a wall body 14 provided so that a flow field FF of the main flow liquid 12 may be in contact with the wall body 14, a fine uneven structure 18 provided on a surface 14A on a side of the flow field FF in the wall body 14, and impregnated liquid 20 held by the fine uneven structure 18. The impregnated liquid 20 has low viscosity in relation to the main flow liquid 12 and is liquid non-compatible with the main flow liquid 12. COPYRIGHT: (C)2010,JPO&INPIT
