PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of preventing sipe wall surfaces opposed each other from being disengaged. SOLUTION: In a sipe 28 of a block formed in a tread part, a ridge line 48 inclined with respect to a sipe depth direction R is formed on one sipe wall surface 29 P. A trough line to be engaged with the ridge line 48 is formed in the other sipe wall surface. A ridge part 52 of the ridge line 48 and a trough part of the trough line are bent halfway to increase an inclination angle with respect to the sipe depth direction R toward the bottom side of the sipe.
