A discharge container equipped with a filter, the discharge container comprising a plug body which has a liquid agent discharge path and is mounted to a mouth of a bottle and also comprising the filter and a check valve which are arranged in the middle of the discharge path, wherein, even if a liquid agent having a large penetration force is contained in the container, a minute amount of the liquid agent having penetrated through the check valve is prevented from reaching the filter to avoid air lock. A containing section (14) for containing a minute amount of a liquid agent having penetrated through a closed check valve (23) is provided between the check valve (23) and a filter (25). This prevents the filter (25) from being wetted with the liquid agent having penetrated through the check valve (23), which is in a closed state, during storage and distribution of a container before the container is used for the first time.
