ABSTRACT:
The present invention relates to a surface mounting crystal oscillator in which an IC chip, a crystal element, and a circuit component are connected together by wire bonding and are housed within a main container having a concave section. The main container has a pair of opposing inner wall step portions along both sides in the longitudinal direction, and this pair of inner wall step portions are also each divided into an upper step portion and a lower-step portion of different heights along the longitudinal direction. At least one of the upper step portions of the pair of inner wall step portions supports one end portion in the lengthwise direction of the crystal element so that the lengthwise direction of the crystal element is aligned in the widthwise direction of the main container. The circuit component is disposed on an inner base surface of the main container below the crystal element.
