Supporting portions 2t and 2t of a rear portion 2z of an applying body holder 2 are advanced into an impregnated body 3 impregnated with a liquid L while a rear portion 4z of an applying body 4 having a plate shape and exhibiting capillarity is supported so as to be sandwiched or wrapped by the supporting portions 2t and 2t. The rear portion 4z of the applying body 4 can therefore be easily inserted into the impregnated body 3 without being bent, while protected by the supporting portions 2t and 2t. The liquid L in the impregnated body 3 is surely moved to the applying body 4, and the liquid L flows straight forward through an opening 2u at a rear end of the supporting portions 2t and 2t, so that the liquid L in the impregnated body 3 is moved smoothly.
