1. A method for evaluating a cure degree of an active energy ray-curable resin composition, the method comprising the steps of: irradiating the active energy ray-curable resin composition with an active energy ray; andevaluating the cure degree of the active energy ray-curable resin composition in accordance with a color and a color value of the active energy ray-curable resin composition,the active energy ray-curable resin composition containing at least a radical polymerization compound, a leuco dye, and a radical polymerization initiator; andwherein a part in which the cure degree of the active energy ray-curable resin composition is evaluated is provided separately from a part to which the active energy ray-curable resin composition is being cured, andwherein, in the step of irradiating, the part in which the cure degree of the active energy ray-curable resin composition is evaluated and the part to which the active energy ray-curable resin composition is being cured are simultaneously irradiated with the active energy ray. 2. The method as set forth in claim 1, wherein the leuco dye is at least one kind selected from the group consisting of leuco crystal violet, leuco malachite green, leuco crystal violet lactone, leuco quinizarine, benzoyl leucomethylene blue, 2′-(2-chloroanilino)-6′-(dibutylamino)fluorane, and 3′,6′-bis(dimethylamino)-2-(4-nitrophenyl)spiro [isoindole-1,9′-xanthene]-3-on. 3. The method as set forth in claim 1, wherein the radical polymerization compound is at least one kind selected from the group consisting of acrylate, methacrylate, vinyl ether, and allyl ether. 4. The method as set forth in claim 1, wherein the cure degree of the active energy ray-curable resin composition is evaluated by measuring the color of the active energy ray-curable resin composition and comparing the color with a reference color. 5. The method as set forth in claim 1, wherein the active energy ray-curable resin composition further contains an inorganic filler. 6. A cure degree evaluation system for evaluating a cure degree of an active energy ray-curable resin composition containing at least a radical polymerization compound, a leuco dye, and a radical polymerization initiator, the cure degree evaluation system comprising: a light source for irradiating the active energy ray-curable resin composition with an active energy ray; andone selected from the group consisting of a color difference meter, a spectrophotometer, and a color luminance meter for evaluating the cure degree of the active energy ray-curable resin composition by measuring a color and a color value of a part in which the cure degree of the active energy ray-curable resin composition is evaluated;wherein a part in which the cure degree of the active energy ray-curable resin composition is evaluated is provided separately from a part to which the active energy ray-curable resin composition is being cured; andwherein the light source simultaneously irradiates, with the active energy ray, the part in which the cure degree of the energy ray-curable resin composition is evaluated and the part to which the active energy rag-curable resin composition is being cured. 7. A method for evaluating a cure degree of an active energy ray-curable resin composition, the method comprising the steps of: carrying out active energy ray irradiation with respect to a cure degree check sheet simultaneously with active energy ray irradiation with respect to a part to which the active energy ray-curable resin composition is applied; andevaluating the cure degree of the active energy ray-curable resin composition in accordance with a color of the cure degree check sheet,wherein the cure degree check sheet comprises a sheet-formed transparent resin material to which a chemical solution containing at least a radical polymerization compound, a leuco dye, and a radical polymerization initiator is applied,wherein the cure degree of the active energy ray-curable resin composition is evaluated by measuring a color value of the active energy ray-curable resin composition; andwherein a part in which the cure degree of the active energy ray-curable resin composition is evaluated is provided separately from a part to which the active energy ray-curable resin composition is to be applied. 8. The method as set forth in claim 7, wherein the cure degree of the active energy ray-curable resin composition is evaluated by comparing the color of the cure degree check sheet and a reference color. 9. The method as set forth in claim 7, wherein the cure degree of the active energy ray-curable resin composition is evaluated by measuring a color value of the cure degree check sheet.
