A tape with snap fastener in which fixing strength of a fastener to a tape main body is secured and which is excellent in durability by eliminating a possibility that the fastener may contact directly the tape upon engagement and disengagement and has good external design performance. A base portion is fixed to front and rear surfaces of the tape main body of the male or female synthetic resin snap fastener, and a substantially cylindrical engaging protruding portion projects vertically from the base portion. A ring-like continuous concave groove portion, which has the same center as the base portion and an inner diameter exceeding the inner diameter of the engaging protruding portion, is provided on any one of front and rear surfaces of the base portion. The engaging protruding portion and the continuous concave groove portion have depth reaching the tape main body.
