Abstract

A venting device for a housing, for example, a battery housing, has a gas-permeable and liquid-impermeable membrane attached to the housing so as to close off a venting opening of the housing. The membrane has a membrane section that overlaps and covers the venting opening. The membrane section has a predetermined bursting pressure. The membrane section deforms without being destroyed when pressure differences between the interior of the housing and the environment occur that are below the bursting pressure and when gas passes through the membrane section.
