To provide a confocal microscope imaging system enabling the simultaneous observations of different Z positions and enabling the speedy measurement of different positions in the direction of the depth of an observation object.

A confocal microscope imaging system 100 having a microscope body 10 having an objective lens 11 comprises: a confocal type first optical system 20 arranged on a first optical path PA1 passing through the objective lens 11 and enabling target observation; and a second optical system 30 arranged on a second optical path PA2 passing through the objective lens 11 and branching from the first optical path PA1, and configured to enable target observation. The position of the first focal face of the objective lens 11 of the second optical system in the direction of its optical axis can be set in a position different from the position of the second focal face of the first optical system in the direction of its optical axis.
