PURPOSE: An integral type guitar and a method for manufacturing the same are provided to improve productivity and to reduce manufacturing cost by forming the integral type guitar using unsaturated polyester. CONSTITUTION: An upper mold and a lower mold engraved with a groove identical to an external appearance of a guitar are fabricated. Then, gel-coat(1) is applied to a surface of the groove. After curing the gel-coat, unsaturated polyester including curing agent and glass fiber are repeatedly deposited on the surface of the groove formed with gel-coat(1). Polyethylene foam or wood is attached to a surface of deposited unsaturated polyester and glass fiber. Adhesive is applied to a peripheral portion of an article included in the upper and lower molds in order to bond the upper and lower mold to each other. Then, the article is ejected from the upper and lower mold.
