Since the metal member having hydrogen permeability lower than that of the material is provided, it is difficult for the metal member to leak from the airtight space and the pressure is not easily reduced. Moreover, the first and second joining members are
Because it is directly joined without passing through a metal member,
Laser welding enables airtight joining without much effort.

となっている。According to a second aspect of the present invention, a metal member having a hydrogen permeability lower than that of the magnetic metal material is provided inside the second joining member forming the airtight space.
It is much more difficult for the hydrogen that is hermetically sealed to leak into the hermetic space, and the pressure of hydrogen is less likely to drop than that described.
