Abstract
The present invention provides a semiconductor strip detector that can reduce noise generated from floating capacitance between electrodes while maintaining high detection efficiency. The semiconductor strip detector for detecting radiation includes: a substrate integrally formed from semiconductor and receiving incident radiation; a first electrode group made up of a plurality of strip-shaped electrodes to provided in parallel to each other on a major surface of the substrate; and a second electrode group made up of a plurality of strip-shaped electrodes to provided coaxially with an orthogonal projection of the plurality of strip-shaped electrodes to of the first electrode group onto the major surface of the substrate, and the electrode groups are formed so that a ratio of a longitudinal length to an electrode-to-electrode length is 10 or more. Therefore, noise can be sufficiently reduced while a detection range is being maintained.
