<p>The purpose of the present invention is to provide an extraction filter and an extraction bag for a beverage including a fine powder of a substance to be extracted such as green tea, with which discharge of the fine powder of the substance to be extracted is inhibited during non-extraction, e.g. during filling of the extraction bag with the substance to be extracted such as tea leaves, or during haulage of the extraction bags having been filled with the substance to be extracted and sealed, and with which discharge of an appropriate amount of the fine powder is caused during extraction. Accordingly, in this extraction filter, a thin-film sheet having, provided therein, cuts piercing a rear surface thereof is provided overlapping a coarse fibre sheet not having cuts provided therein. Furthermore, this extraction bag is provided with a bag main body formed using the extraction filter.</p> |
