The invention provides a linear grid condom. The linear grid condom comprises a top-end semen storage bag, a middle-end condom body and a tail-end elastic rubber ring, wherein the outer wall of the condom body is provided with linear convex grids; and grid shapes of the linear convex grids are rhombus, triangle, circle, ellipse, square, rectangle or polygon. The linear convex grids are fully distributed on the outer surface of the condom body of the condom, so that the condom has better tensile strength and is difficult to rupture in high-intensity exercise to avoid the failure of contraception; and the convex grid design strengthens friction force, and the convex grids stimulate vaginas at different positions in the vaginas in the process of sexual life, so that the pleasant sensation of the female is increased, the phenomenon that the orgasm of the female appears more later and more slowly is effectively avoided, the harmony of the orgasm of the male and the female is realized, and the problems that inner walls of the vaginas relax and the pleasant sensation is difficult to produce due to the age growth of the female are effectively solved.
