ABSTRACT:
An acoustic wave type touch panel is equipped with: a substrate that objects contact; reflective arrays having a great number of inclined lines provided on the substrate; acoustic wave generating sections provided on the substrate; and detecting sections provided on the substrate. An array of micro reflectors, which are shorter than the inclined lines, for attenuating spurious waves generated by reflection of the acoustic waves by the reflective arrays, is provided in the reflective array regions between the inclined lines at least one end thereof.
