1. An artificial marble comprising:
a first surface of the artificial marble comprising one or more striped regions and a base region, and a second surface facing the first surface,
wherein the stripe regions extend into the artificial marble,
wherein the artificial marble comprises a section where a surface of the section corresponding to the first surface of the artificial marble is the base region and an inside of the artificial marble in a vertical direction under the base region is the stripe region,
wherein at least a part of the stripe region of the section is visible to a naked eye from the surface of the base region,
wherein the base region comprises 550 to 650 parts by weight of inorganic particles and 250 to 350 parts by weight of quartz powder on the basis of 100 parts by weight of a binder resin,
wherein the binder resin comprises an unsaturated polyester resin in an amount of 90% by weight or more,
wherein the unsaturated polyester resin is manufactured using a composition comprising an unsaturated polyester polymer and a vinylic monomer in a weight ratio of 100:30 to 70, and
wherein the quartz powder has an average SiO2 content of 99.5% by weight or more and 100% by weight or less.
