摘要： Quartz-crystal vibrating devices are disclosed, including vibrating and frame portions separated by a through-slot. An edge surface of the slot has a protrusion preventing unwanted formation of artifact “electrodes.” The vibrating portion and frame are made of AT-cut quartz as a unit. A joining portion couples the frame and vibrating portion together across the through-slot. A package base has two external electrodes. A third frame region has first and second plane surfaces. The protrusion projects toward the vibrating portion and has first and/or second sloped surfaces. First and second extraction electrodes extend from respective excitation electrodes via respective joining portions to respective external electrodes. The extraction electrodes pass across the first plane surface and first sloped surface or across the second plane surface and second slanted surface.
