The present invention provides a vibration-insulating rubber molded product having flash, where a thicker portion of the flash can be easily evaluated by visually observing a light-transmittance thereof to prevent the product from 5 cracking, and to find damage of a mold used for forming the product with ease. The vibration-insulating rubber molded product of the present invention comprises a rubber component, a silica powder and a carbon black. The content of the carbon black is determined such that (a) a portion having a thickness of 1 mm or less in the flash is substantially transparent or translucent with white or gray color, and that (b) a portion having a thickness of 2 mm or more in the flash is substantially opaque with black color, whereby whether the flash includes a portion having a thickness of 2 mm or more can be evaluated by visual observation.
