The present invention addresses the problem of providing a technique which is capable of easily forming a resin opening of a desired shape. As a solution, a base (18) which has a first surface region (12) and a second surface region (14) around the first surface region (12), and which is provided with a wiring line (16) is prepared. Subsequently, a resist (20) which covers the first surface region (12) is formed. Then, the first surface region (12) and the second surface region (14) are covered with a resin body (22) such that the resist (20) is contained therein, and the resist (20) is exposed from the resin body (22). After that, the exposed resist (20) is removed, so that a resin opening, from which the base (18) in the first surface region (12) is exposed, is formed in the resin body (22). |
