An artificial marble is provided to have a low content of monomer remaining in final products, be easily curable, and have improved workability because an offensive odor is not emitted during a sanding work. A method for manufacturing artificial marble includes the steps of: adding a reaction accelerator and an initiator mixture to an acrylic resin syrup to prepare an artificial marble slurry, wherein the initiator mixture comprises (A) an initiator to be decomposed by the reaction accelerator and (B) a thermally labile initiator; and hardening the artificial marble slurry. The reaction accelerator is a metal hydroxide or mercaptan. The initiator(A) is selected from the group consisting of t-butyl peroxymaleate, t-butyl peroxyacetate, and a mixture thereof. The thermally labile initiator(B) is selected from the group consisting of benzoyl peroxide, lauroyl peroxide, butyl hydroperoxide, cumyl hydroperoxide, t-butyl peroxyhexanoate, and mixtures thereof.
