  We present the discovery of new star clusters in the central plane region
($|l|<30\deg$ and $|b|<6\deg$) of the Milky Way. In order to overcome the
extinction problem and the spatial limit of previous surveys, we use the
Wide-field Infrared Survey Explorer (WISE) data to find clusters. We also use
other infrared survey data in the archive for additional analysis. We find 923
new clusters, of which 202 clusters are embedded clusters. These clusters are
concentrated toward the Galactic plane and show a symmetric distribution with
respect to the Galactic latitude. The embedded clusters show a stronger
concentration to the Galactic plane than the non-embedded clusters. The new
clusters are found more in the first Galactic quadrant, while previously known
clusters are found more in the fourth Galactic quadrant. The spatial
distribution of the combined sample of known clusters and new clusters is
approximately symmetric with respect to the Galactic longitude. We estimate
reddenings, distances, and relative ages of the 15 class A clusters using
theoretical isochrones. Ten of them are relatively old (age $>800$ Myr) and
five are young (age $\approx4$ Myr).
