To provide a detector having improved detecting sensitivity and accuracy when utilizing the electron multiplying operation by gas.
The radiation detector 1 utilizing the electron multiplying operation by gas comprises: an inorganic-material substrate 7 for forming an electric field in through-holes 9 passing through between both faces by giving a potential difference between both faces; and electron multiplying parts 3a, 3b having two metal thin films 8 formed on both faces of the substrate 7. The substrate 7 has the through-holes 9 formed passing through between the two metal thin films 8 after forming the two metal thin films 8. Thus, the concentration of gas in a casing 2 of the detector can be stabilized to improve the detecting accuracy of incident light and reduce the possibility that multiplied electrons E2, E3 are trapped by metal, thereby improving detecting sensitivity.
