PROBLEM TO BE SOLVED: To suppress the occurrence of spurious that easily occur with frequency increase. SOLUTION: A crystal oscillating piece 2 provided in a package 3 is constructed by forming exciting electrodes 42 and 43 on both principal surfaces 411 and 412 of a substrate 41. The exciting electrodes 42 and 43 are comprised of main electrodes 44 and 45 formed on both the principal surfaces 411 and 412, lead out electrodes 46 and 47 extending from the main electrodes 44 and 45 for connection with the outside, and auxiliary electrodes 48 and 49 of which the center of gravity is approximately the same as the main electrodes 44 and 45. The exciting electrodes 42 and 43 are formed on both the principal surfaces 411 and 412 using photolithography techniques. Furthermore, the dimensions of the auxiliary electrodes 48 and 49 are designed to be thinner and smaller in a surface area than the main electrodes 44 and 45. COPYRIGHT: (C)2006,JPO&NCIPI
