PURPOSE:To obtain a package for electronic parts, which can reliably prevent a brazing material flowing out from the part where the package is brazed from flowing into the welding part where hard glass of the package is welded. CONSTITUTION:In a package for electronic parts, a barrier layer 70 difficult to wet with a brazing material is formed on the end surface of a cylinder body 24 which is the surface on the package member between an outer surface of the cylinder body 24 which is the part where a package is brazed and a stepped surface 26 of the inner periphery inside of the cylinder body which is the welding part where hard glass is welded.
