摘 要：
A particle counter 10 comprises an electrical charge generation element, a collecting device and a number
measuring device. The charge generation element applies electric charges
generated by discharge to particles in a gas that is introduced into a gas flow line 12 to form charged particles. The collecting device collects the charged particles on a collecting electrode 48
using an electric field generated by a field generator 42. The number measuring device detects the number of charged particles based on a physical size at the collecting electrode 48, the physical size varying depending on the number of charged particles collected by the
collecting electrode 48. The gas flow line 12 has a skeleton-forming section 13 (13a to 13d), which is formed from a ceramic material and is tight, and a stress-relieving section 14 (14a to 14d), which is
