Spacer

Abstract

Provided is a spacer which is applicable even when there are a plurality of dimensions with respect to a gap and which also can be easily miniaturized. The spacer comprises a base material contact part and a plurality of component contact parts. The base material contact part is directed in the z-axis negative direction, and comes into contact with a portion directed in the z-axis positive direction in a base material. Each of the component contact parts is directed in the z-axis positive direction, and any one of the component contact parts comes into contact with a portion directed in the z-axis negative direction in a component. The plurality of component contact parts are arranged at positions such that the distance in the z-axis direction between the component and the base material in contact with the base material contact part changes depending on which one of the component contact parts comes into contact with the component.
