A particulate material detecting apparatus (100) is provided with a detecting apparatus main body (1) having a cavity (2) penetrating inside. In the cavity (2), a particle charging section (3), a dust collecting section (4) and an ion wind generating section (5) are arranged in this order from the side of one end section (flow-in side end section)(6) of the cavity. The particle charging section charges a particulate material flowed into the cavity from the flow-in side end section (6). The dust collecting section captures the particulate material charged by the particle charging section (3) and measures the mass of the particulate material. The ion wind generating section moves the particulate material charged by the particle charging section (3) toward the other end section (flow-out side end section) (7) of the cavity (2). The particulate material detecting apparatus which is small, has a small measuring error and can be easily manufactured at low cost is provided. |
