Abstract
A joint structure jointing a ceramic member and a metal member is a joint structure jointing a ceramic member and a metal member that are provided in a device provided on a portion through which gas passes. The joint structure has a joint portion that joints the ceramic member and the metal member. The joint portion includes a glass portion made of a glass and a metal solder portion having higher corrosion resistance with respect to the gas than the glass. An area where the metal solder portion contacts to the gas is larger than an area where the glass portion contacts to the gas.
