The invention belongs to the technical field of birth control and particularly relates to a condom and a manufacturing method thereof. The head area of the condom is thicker than other areas. The head area of the condom is a 30-40 mm area from the top end of a condom sperm storage bag. The manufacturing method includes: an overall impregnation area of a condom die passes through a hot water tank to arrive at impregnation temperature, the head of the condom die passes through a hot water tank with higher temperature, and then the condom die enters natural rubber whey of a first tank to be soaked and then is soaked in natural rubber whey of a second tank. The condom with the thickened head can effectively reduce man sexual excitation through a screen hindering method and prolong sexual life time.
