[1] An external skin preparation for IR protection, an external skin preparation for heat insulation, an external skin preparation for photoaging prevention, an external preparation for skin temperature increase prevention, an external skin preparation for fatigue prevention and an external skin preparation for active oxygen production prevention, containing a tabular metal oxide (A) having a thickness of 30 to 360 nm, and [2] an external skin preparation containing a tabular metal oxide (A) having a thickness of 30 nm or more and 360 nm or less and an aspect ratio of 50 or more and 300 or less, and a nonvolatile oil (B) in a ratio by mass [(A)/(B)] of 0.05 to 5.

External preparation

A fiber collection tool for collecting a fiber spun by electrospinning is described. The fiber collection tool has a size holdable by the hand of a user, and includes, in its interior, an electroconductive section. Preferably, the fiber collection tool further includes a surface section outside the electroconductive section. In a fiber deposit production method, a user collects, with the fiber collection tool, a fiber spun by the user by performing electrospinning using an electrospinning device having a size holdable by the hand of the user, and thereby produces a film including a deposit of the fiber on a surface of the fiber collection tool. The fiber collection tool, having the deposit formed thereon, is pressed against a surface of an object, and the deposit is transferred onto the surface of the object, to form a film including the fiber deposit on the surface of the object.

A fiber collection tool for collecting a fiber spun by electrospinning is described. The fiber collection tool has a size holdable by the hand of a user, and includes, in at least a portion of the surface thereof, an electroconductive section having a surface electrical resistivity of 10&#x3a9;/cmor less, or a hydrophilic section having a water contact angle of preferably from 15&#xb0; to 90&#xb0; at 25&#xb0; C. A user collects, with the fiber collection tool, a fiber spun by the user by electrospinning using an electrospinning device having a size holdable by the hand of the user, and thereby produces a film including a deposit of the fiber on a surface of the fiber collection tool. The fiber collection tool, having the deposit formed thereon, is pressed against a surface of an object, and the deposit is transferred onto the surface of the object, to form a film including the fiber deposit on the surface of the object.
