Title:
PIEZOELECTRIC OSCILLATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/053836
Kind Code:
A1
Abstract:
Provided is a piezoelectric oscillation device that can firmly join to an external substrate at a location as close to the external substrate as possible. Provided is a piezoelectric oscillation device 1 in which at least an oscillator 2 and an integrated circuit element 10 having an oscillation-generating circuit are mounted on a substrate 11 having a wiring pattern that includes a plurality of pads on a first mounting surface 11a, which is one main surface of a pair of main surfaces, the substrate 11 also having an external connection terminal 11d that is electrically connected to a wiring pattern on a second mounting surface 11b, which is the other main surface parallel to the one main surface, and that is electrically connected to an external substrate P. The substrate 11 has a recess 11g in the second mounting surface 11b. The external connection terminal 11d is located within the recess 11g and a gap G is provided between the outer edges of the external connection terminal 11d and the side surfaces 11i of the recess 11g.
