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.

According to one embodiment, a mold includes a base material, a pedestal portion and a pattern portion. The base material includes a first surface and a second surface. The pedestal portion protruded from the first surface of the base material and includes a side surface. The pattern portion is provided in the pedestal portion and includes an concave-convex pattern. The pedestal portion includes a first region and a second region. The first region is provided with the concave-convex pattern. The second region is provided between the first region and the side surface. The second region has maximum height equal to maximum height of the first region. The second region has a first height of the second region on the side surface side and a second height of the second region on the first region side. The first height is lower than the second height.
