    Abstract: According to one embodiment, a sealed chemical container has a bonding area where a flexible sheet-like member is firmly bonded onto a plate, and the bonding area defines a first compartment which can be swollen and an outflow passage which communicates with the first compartment via an opening. A first seal portion is weakly bonded onto the plate compared to the bonding area to define the first compartment to block communication between the first compartment and an outflow passage. The first seal portion is peeled off by an increase in internal pressure in the first compartment to allow communication between the first compartment and the outflow passage.
