The invention provides a multilayer ceramic microwave band pass filter, and belongs to the technical field of microwave functional device. The multilayer ceramic microwave band pass filter includes a terminal electrode and a two grounding metal layers located in a dielectric layer. Four UIR structures spaced on the same plane are disposed between the two grounding metal layers. The four UIR structures are all broadside-coupled multilayer strip line structures. The coupling between the first level UIR structure and the fourth level UIR structure are enhanced by setting a first coupling enhancement metal layer. The coupling among the four UIR structure is enhanced by setting a second coupling enhancement metal layer. The first level UIR structure and the fourth level UIR structure are respectively provided with input and output ends for external connection with a circuit. According to the invention, by the design of the novel coupling structure, the energy loss can be reduced, the insertion loss in the pass-band is thus reduced, and a miniaturized microwave filter with low frequency, small in-band fluctuation, no spurious passband and good out of band suppression can be achieved.
