TEST METHOD OF MICROSTRUCTURE BODY AND MICROMACHINE
First Claim
1. A method for testing a microstructure body including a first conductive layer, a second conductive layer, and a sacrifice layer or a space provided between the first conductive layer and the second conductive layer, comprising the steps of:
- connecting the first conductive layer to a first pad;
connecting the second conductive layer to a second pad;
supplying electric power to the microstructure body from the first pad and the second pad; and
detecting an electromagnetic wave generated from an antenna connected to the microstructure body as a characteristic of the microstructure body.

Abstract
It is an object to provide a test method of a process, an electric characteristic, and a mechanical characteristic of a structure body in a micromachine without contact. A structure body including a first conductive layer, a second conductive layer provided in parallel to the first conductive layer, and a sacrifice layer or a space provided between the first conductive layer and the second conductive layer is provided; an antenna connected to the structure body is provided; electric power is supplied to the structure body wirelessly through the antenna; and an electromagnetic wave generated from the antenna is detected as a characteristic of the structure body.
