Liquid-sealed mount

A liquid-sealed mount comprising:

• a body having one end closed by a body rubber and the other end closed by a diaphragm;
• a membrane that partitions an inside of the body into a first liquid chamber and a second liquid chamber;
• a plurality of crosspieces placed on both sides in an axial direction of the membrane with the membrane therebetween, and extending radially with a predetermined point as a center;
• and
• a passage that communicates the first liquid chamber and the second liquid chamber, wherein
• the membrane has at least one protrusion group formed from a plurality of protrusions placed on a circle which is approximately concentric with the predetermined point, and
• the at least one protrusion group satisfies a condition of y>2x+2a when an average value of spacing between protrusions adjacent in a circumferential direction is x, a diameter of the protrusion is a, and a width of the crosspiece is y.
