To provide an indoor dust collector preventing intrusion and deposition of dust in non-deposition regions by a dust collecting air current.
The indoor dust collector includes: a dust collecting part 4 generating the dust collecting air current in an overall indoor space to collect floating dust; and air curtain parts 5A, 5B for generating cut-off air currents 10A, 10B, respectively. The air curtain parts 5A, 5B are arranged around the non-deposition regions 7A, 7B which are shadowed regions viewed from the upper side and to which dust is not dropped down when the dust collecting air is not generated. Through the operation of the air curtain parts 5A, 5B arranged around the non-deposition regions 7A, 7B, the dust collecting air current generated by the dust collecting part 4 prevents intrusion and deposition of dust in the non-deposition regions 7A, 7B, and dust in the overall indoor space is collected while the non-deposition regions 7A, 7B are kept clean.
