Abstract
The present invention relates to a thickness gauge which comprises a plurality of metallic sheets made to have standard thickness, a U-shaped frame and a screw which adjusts tightness of the metallic sheets. The present invention is characterized in that each metallic sheet comprises a hole and that the hole positions of any two neighboring metallic sheets are different; when two or more pieces of metallic sheets overlap, the holes of the metallic sheets will be shielded by other metallic sheet and human eyes can not see through the holes. In another preferred embodiment, the thickness gauge is characterized in that there is a cut at each metallic sheet. Whereby users can distinguish clearly and conveniently one metallic sheet from several metallic sheets overlapping together and could avoid misuse and measurement errors.
