A light-weighted prepreg is composed of a sheet-shaped cork material of which opposite surfaces are coated with a resin and a fiber reinforced composite resin layer laminated on at least one surface of the sheet-shaped cork material. The light-weighted prepreg assures that a grip portion or a holder portion having a predetermined diameter is molded with minimized increase of weight while exhibiting excellent shock absorbing properties and gripping or holding comfortability at the time of practical use.

An elongated lightweight fiber reinforced composite resin pultrusion-formed piece with a rectangular structural shape has an elongated light honeycomb structure body with a rectangular sectional shape and at least one fiber reinforced resin layer formed to cover at least a portion of the outer peripheral surface of the lightweight honeycomb structure body. The fiber reinforced resin layer comprises an axial fiber layer formed by aligning reinforcing fibers parallel to the longitudinal axis of the lightweight honeycomb structure body.
