In one embodiment, a pattern formation method is disclosed. The method can place a liquid resin material on a workpiece substrate. The method can press a template against the resin material and measuring distance between a lower surface of a projection of the template and an upper surface of the workpiece substrate. The template includes a pattern formation region and a circumferential region around the pattern formation region. A pattern for circuit pattern formation is formed in the pattern formation region and the projection is formed in the circumferential region. The method can form a resin pattern by curing the resin material in a state of pressing the template. In addition, the method can separate the template from the resin pattern.
