A headwear using a sheet adhering to aluminum bits, comprises a crown main body having a plurality of panels, a visor portion attached to a forward portion of the peripheral edge of the crown, and a size adjuster attached to an underside of the rear part of the crown. Furthermore, attached to the said headwear and/or the visor portion is a light-reflecting and seemingly luminescent sheet adhering to aluminum bits made in the shapes of numbers, letters, figures and drawings to express logotypes and emblems. The source of the said seeming luminescence is a transparent vinyl sheet and tiny polygon-shaped aluminum bits densely attached to the sheet. A logotype or emblem made of the said sheet adhering to aluminum bits reflects light and thus create the seeming luminescence, stimulating the user's aesthetic sense and raising the product value.
