摘要： A crystal unit includes an AT-cut crystal element and a container. The AT-cut crystal element has an approximately rectangular planar shape. The AT-cut crystal element includes a first inclined portion, second inclined portions, and a first secured portion. The first inclined portion is inclined such that the crystal element decreases in thickness from a proximity of the first side to the first side. The second inclined portions are disposed on respective both ends of the first side, the second inclined portions being formed integrally with the first inclined portion. The second inclined portions are inclined gentler than the first inclined portion. The first secured portion and a second secured portion are formed integrally with the second inclined portion. The first secured portion and the second secured portion each project out from the first side to outside the crystal element to be used for securing with the securing members.

摘要： A crystal unit includes an AT-cut crystal element, excitation electrodes, extraction electrodes. The AT-cut crystal element has an approximately rectangular planar shape. The excitation electrodes are disposed on front and back of principal surfaces of the AT-cut crystal element. The extraction electrodes are extended from the excitation electrodes to a side of one side of the AT-cut crystal element via a side surface of the AT-cut crystal element. Assuming that an extraction angle of the extraction electrode from the principal surface to the side surface is defined as an angle θ with respect to an X-axis of a crystallographic axis of a crystal, the angle θ is equal to or greater than 59 degrees and equal to or less than 87 degrees.
