PROBLEM TO BE SOLVED: To provide a particle/photon detector compatibly having a high response speed, a large sensitive area, less heat generation, and high signal strength, while capable of preventing generation of a non-sensing region.SOLUTION: When particles or photons collide with a detection unit 12 that is retained in a superconductive state to transfer the detection unit to a normal conductive state, a particle/photon detector 10 outputs an electric signal indicating a detection of particles or photons. The particle/photon detector 10 includes: a plurality of detection units 12 connected in series; and two wiring lines 26 and 28 arranged in parallel that are provided in parallel with the plurality of detection units 12 that are connected in series. Respective connection parts of adjacent detection units 12 are alternately connected to the two wiring lines 26 and 28 arranged in parallel via resistors 14, and electric signals from the plurality of detection units are read through at least one of the two wiring lines 26 and 28 arranged in parallel. |
