。[Claims for Utility Model Registration] (1) A detection unit connected to a power source and placed in a liquid passageway, which increases electrical resistance when detecting a specific liquid in the passageway, and a detection unit formed of a shape memory alloy. The present invention is characterized by comprising: a valve opening/closing body whose shape changes due to heat generation when the electrical resistance value of the detection section increases; and a valve body which opens/closes within the passage as the shape of the valve opening/closing body changes. Liquid supply control device. (2) The liquid supply control device according to claim 1, wherein the specific liquid is gasoline. (3) The liquid supply control device according to claim 1, wherein the passage is a fuel supply pipe leading from the fuel filler port of the vehicle to the fuel tank. (4) The liquid supply control device according to claim 1, in which the valve opening/closing body and the valve body are integrally molded. (5) The liquid supply control device according to claim 1, wherein the detection section is constituted by an element in which carbon particles are embedded in porous polytetrafluoroethylene. (6) The liquid supply control device according to claim 1, wherein the detection section is constituted by an element in which carbon particles are embedded in foamed fluorinated ethylene propylene.
