The present invention relates to a cup holder with an improved insulation property. More specifically, a plurality of linear protrusion curved surfaces are formed on a surface of the holder to improve an insulation property and simultaneously, improve a gripping feeling. The cup holder comprises: a base cardboard (12) having an inner surface with which a circumferential surface of a cup is in contact; and a contact cardboard (11) attached to an outer surface of the base cardboard (11) and having the linear protrusion curved surfaces (111) formed in a longitudinal direction of the cup on the outer surface. At least a portion of each linear protrusion curved surfaces (111) is spaced from the base cardboard (12) to form an air flow passage (111a). |
