PROBLEM TO BE SOLVED: To perform sticking hardening having uniformity of a whole surface and to increase operation speed by irradiating a base material with ultraviolet rays while rotating it and controlling unevenness of irradiation of ultraviolet rays. SOLUTION: A base material W1 of one side is held and fixed on a holding member 1 by vacuum-absorption, after deenergizing, adhesive of ultraviolet hardening resin is dropped on the base material W1 while rotating the holding member 1 at low speed and applied in a ring doughnut shape, a base material W2 of the other side is overlapped on the base material W1 concentrically. Successively, adhesive is widened evenly between base materials W1 , W2 by centrifugal force by pressing the holding member 1 with a vertical motion mechanism and rotating the holding member 1 at high speed, while after disgorging of surplus adhesive, ultraviolet rays are irradiated to adhesive by an ultraviolet ray lamp 11 while rotating the holding member 11 at low speed with a rotation mechanism 4, and adhesive is hardened. Successively, dirt of adhesive and the like is cleaned, a overlapping process of a series of a base material can be quickly performed by repeating these operations.
