Abstract:
1. A method of manufacturing a microdevice having a laminated structure comprising one or more resin layers (X) having a cut portion, said resin layers being laminated with another member or another resin layer (X) to form a cavity composed of the cut portion, said method comprising: (i) the step (i) of applying an active energy ray curable composition (x) containing a radiation polymerizable compound (a) on a coating substrate to form an uncured coating film, (ii) the step (ii) of irradiating a portion of the uncured coating film with an active energy ray, thereby making the active energy ray curable composition in the portion of the film non-flowable or slightly flowable, and semi-cured to such an extent that unreacted active energy ray polymerizable functional groups in the composition can remain, wherein the portion, and a non-irradiated portion of the film, which serves as the cut portion, constitute a semi-cured coating film, (iii) the step (iii) of removing the uncured composition (x) of the non-irradiated portion from the semi-cured coating film to obtain a semi-cured coating film having a cut portion of the coating film, (iv) the step (iv) of laminating the semi-cured coating film having a cut portion with another member (J) to form a resin layer (X), (v) the step (v) of removing the coating substrate from the resin layer (X), thereby transfering the resin layer (X) onto the member (J), and (vi) the step (vi) of irradiating the resin layer (X) in a semi-cured state with an active energy ray, thereby further curing the resin later (X) and bonding the resin layer (X) with the member (J) after the step (iv) and before and/or after the step (v).
