Abstract
A crystal oscillator includes a surface mount type crystal unit and a mounting substrate. The surface mount type crystal unit includes a ceramic container. The surface mount type crystal unit has a rectangular shape as a planar shape. The mounting substrate includes a ceramic substrate on which an electronic component is mounted, the mounting substrate having a rectangular shape as a planar shape. The crystal oscillator has a structure where the surface mount type crystal unit and the mounting substrate are laminated, and both terminals of the surface mount type crystal unit and the mounting substrate are connected with a bonding material. The mounting substrate and the surface mount type crystal unit are connected in a positional relationship where a long side of the mounting substrate and a long side of the surface mount type crystal unit are orthogonal.
