SOLUTION: A crystal oscillator 1 is obtained by housing the electronic parts body of a crystal piece 2, etc. in the ceramic package 7 and connecting by brazing a lid 3 to the peripheral edge 7b of the opening of the ceramic package 7. As the lid 3, a lid having a recess 3a is used. The lid 3 is disposed on the ceramic package 7 so that the recess 3a is bridged between both the peripheral edge 7b of the opening and a cavity 7c, and the both are connected by brazing.
