摘要： The metal base for a crystal unit includes: a base body in which at least a pair of through-holes are formed; a pair of leads provided with a supporter for supporting a crystal blank at the head thereof; and glass charged into the respective through-holes to electrically insulate the leads from the base body and hermetically seal the through-holes. A step is formed in a region of the lead corresponding to the outer bottom surface of the base body, the lead is made up of at least a first lead portion on the through-hole side from the step and a second lead portion in a direction in which the lead extends out from the step. The diameter of the lead of the second lead portion is smaller than the diameter of the lead of the first lead portion.

摘要： A quartz crystal element in which unwanted response is suppressed, comprising a thickness shear quartz blank such as an AT-cut type. An area where an amplitude of unwanted response may be strong can be eliminated from the quartz blank by forming the quartz blank into a substantially hexagon. Preferably, each pair of three pairs of opposite sides are mutually parallel and one of the pairs is parallel to the longest diagonal line of the quartz blank. For an AT-cut type of quartz crystal element, the direction of the longest diagonal line of the quartz blank is within the range of 28.degree..+-.15.degree. or 118.degree..+-.15.degree. from the Z' axis direction of the quartz blank, and the quartz blank is held at the ends of the longest diagonal line.
