PROBLEM TO BE SOLVED: To provide a piezoelectric vibration device which prevents the occurence of cracks due to a thermal expansion coefficient difference and achieves high airtight reliability, and to provide a manufacturing method of the piezoelectric vibration device.SOLUTION: A crystal resonator 1 of this invention comprises: a lid 4; a crystal vibration piece 3; and a container 2 housing the crystal vibration piece 3. A resin film for printing 9 is formed on one main surface 41 of the lid 4, and a stress relaxation film 10 for relaxing stress applied on the lid 4 is formed on the other main surface 42 facing the one main surface 41. |
