PURPOSE: To reduce a manufacturing cost, by a method wherein line layers, having non-heat resisting lines abutted on heat resisting lines for connection, and tow random layers are alternately laminated, and they are formed physically integrally in a manner that the outermost layer forms the web layer.

CONSTITUTION: The wick of a combustion device consists of a wick body 1, a heat resisting combustion part 2 and a fuel suction part 3. The heat resisting combustion part 2 is constituted such that plural line layers 1a, having heat resisting lines layers 2a abutted on non-heat resisting line layers 3a for junction, and plural tow random web layers 1b are alternately laminated, and the outermost layer forms the web layer 1b. In order to prevent exfoliation of the two different layers, they are formed physically integrally by use of a needle punch, and the line layers 1a are aligned in a seamless manner over the entire length of the wick body 1. This allows promotion of a fuel suction and shortening of a fire-extinguishing time.
