Induction type transducer and electronic caliper |
| 摘要 |
An induction type transducer is formed at a substrate of a grid assembly which is disposed so as to be opposed to a scale. The surface of the substrate opposed to the scale is made flat, and even if a liquid enters from a gap between the grid and the scale, permeation of the liquid into the substrate is prevented.
