Abstract
A joint body according to the invention is strong for a heat cycle and generates no local cracks. The joint body has the following features. An end portion of the metal member and the ceramic member are connected via a metal connection portion. The metal connection portion has a metallized layer formed on the ceramic member and a brazing connection portion interposing at least between the metallized layer and an end portion of the metal member. A melt point of a brazing member constructing the brazing connection portion is lower than that of a brazing member constructing the metallized layer.
