Provided is a method for producing a fiber-reinforced composite material having high heat resistance and excellent quality of appearance. Disclosed is a method for producing a fiber-reinforced composite material, the method comprising: arranging, in a shaping mold, a prepreg made by impregnating reinforcing fibers with an epoxy resin composition; pressurizing and heating the prepreg at a pressurefrom 0.2 to 2.5 MPa and a temperature from 130 to 200 DEG C as primary curing; and then further heating the prepreg at a temperature from 210 to 270 DEG C for at least 10 minutes as secondary curing. 提供一种高耐热性和外观品质优异的纤维增强复合材料的制造方法。一种纤维增强复合材料的制造方法，其中，将环氧树脂组合物浸渗于增强纤维而成的预浸料配置于成型模具内，作为一次固化，以0.2～2.5MPa、130～200℃加压加热后，作为二次固化，在210～270℃进一步加热10分钟以上。
