PROBLEM TO BE SOLVED: To provide a curing device hardening an active energy line curable composition having enough curability to gain solid physical character by irradiating active energy line with a UV-LED light source having peak wave-length at 200-420 nm.SOLUTION: A curing device equips with a light source unit hardening an active energy line curable composition containing an active energy line polymerizable compound having an ethylenic double bond (A) and a photoinitiator (B). The unit is a UV-LED light source unit that more than two kinds of light source semiconductor element having different emission wavelength is combined.SELECTED DRAWING: Figure 1 |
