1. A substrate supporting vibration structure which is a vibration structure for supporting a substrate, comprising:
a spacer member, fixed between a first substrate and a second substrate, having at least one form selected from a pillar form and a long strip form; and
a piezoelectric element, formed at a predetermined position between the first substrate and the second substrate or at a predetermined position of the long strip-form portion of the spacer member, having a vibration supporting portion and a vibration applying portion,
wherein the vibration supporting portion and vibration applying portion of the piezoelectric element are disposed in the thicknesswise direction of the first and second substrates stacked, wherein:
the spacer member having a long strip form has formed therein a part fitting site having an internal hollow form,
the vibration supporting portion is joined to a bottom of the part fitting site, and
the vibration applying portion is joined to a top of the part fitting site.
