In a so-called step-and-repeat method in which a mask pattern is circumferentially written by exposure onto each predetermined region on a surface of a roller mold, an object of the present invention is to improve the spacing accuracy between the mask patterns and to suppress the occurrence of misalignment at a seam when the mask pattern has been written onto a 360-degree circumference. For that object, a roller mold manufacturing apparatus according to the present invention comprises: a mask 3 having a function of transmitting part of an irradiating substance; a rotational drive apparatus that rotates a roller mold 100 around a rotational shaft; a rotation amount detection sensor that detects an amount of rotation; a control apparatus that sends a control signal for adjusting a circumferential position of writing onto a resist of the roller mold with the irradiating substance; and an actuator 7 that moves the mask 3 linearly, wherein a predetermined area is irradiated with the irradiating substance in a state where rotation of the roller mold 100 is stopped, the roller mold 100 is then rotated by a predetermined amount and stopped, and a circumferential position of writing is adjusted for irradiating another predetermined area with the irradiating substance. |
