The purpose of the present invention is to provide a production method for a laminate film which has been accurately precut to the desired shape. This production method is for a laminate film having an elongated release film furnished thereon with a plurality of insular self-adhesive films including an insular self-adhesive film (A) with an insular self-adhesive film (B) which are mutually adjacent in the lengthwise direction, the method including: a step of obtaining an elongated laminate having a release film and a self-adhesive film; a step of precutting the self-adhesive film of the laminate to obtain a first peeling portion; and a step of peeling the first peeling portion from the release film. The first peeling portion includes a peripheral edge portion (A1) of the insular self-adhesive film (A) at a first widthwise edge of the release film, a peripheral edge portion (B2) of the insular self-adhesive film (B) at the other widthwise edge of the release film, and a linking portion (C) linking the peripheral edge portion (A1) and the peripheral edge portion (B2), but does not include a peripheral edge portion (A2) of the insular self-adhesive film (A) at the other widthwise edge of the release film, or a peripheral edge portion (B1) of the insular self-adhesive film (B) at the first widthwise edge of the release film. |
