To provide a method for manufacturing a grinding wheel capable of efficiently burying and fixing a grindstone in a groove formed in an annular wheel base, and the grinding wheel.SOLUTION: The method for manufacturing the grinding wheel comprises: a mixture generation step of mixing a liquid ultraviolet curable resin and a liquid anaerobic resin to generate a mixture 23; a mixture filling step of filling an annular groove 15 of an annular wheel base 11 having, formed at an end surface 14, the groove 15 in which a grindstone 12 is buried, with the mixture 23; a grindstone insertion step of inserting the grindstone 12 in the groove 15 filled with the mixture 23 such that one end 16 side of the grindstone 12 is buried in the groove 15 and the other end 17 side of the grindstone 12 projects from the end surface 14; and a curing step of applying an ultraviolet ray 31 toward the end surface 14 to cure the mixture 23. The mixture 23 is cured by two functions of anaerobic resin curing by air cutting-off and ultraviolet curable resin curing by ultraviolet ray application.SELECTED DRAWING: Figure 9 【課題】効率よく円環状のホイール基台に形成された溝部に砥石を埋設し固定できる研削ホイールの作製方法及び研削ホイールを提供すること。【解決手段】研削ホイールの作製方法は、液状の紫外線硬化樹脂と液状の嫌気性樹脂とを混合させ混合剤２３を作成する混合剤作成ステップと、砥石１２が埋設される環状の溝部１５が端面１４に形成された円環状のホイール基台１１の溝部１５に混合剤２３を充填する混合剤充填ステップと、砥石１２の一端１６側を溝部１５に埋設し砥石１２の他端１７側が端面１４から突出するように、混合剤２３が充填された溝部１５に砥石１２を挿入する砥石挿入ステップと、端面１４に向かって紫外線３１を照射し、混合剤２３を硬化させる硬化ステップと、を備え、空気遮断による嫌気性樹脂の硬化と、紫外線照射による紫外線硬化樹脂の硬化と、の２つの作用によって混合剤２３を硬化させる。【選択図】図９
