A brake pad state estimation device (100) estimates a brake pad state (ST) including at least one of a wear volume (W) and a temperature (Te) of a brake pad (30) of a vehicle (1). The brake pad state estimation device (100) performs: a brake pad state calculation process calculating the brake pad state (ST) based on sensor detection information (210) during braking; and an information output process storing the brake pad state (ST) information in a storage (102) and/or transmitting the brake pad state (ST) information to the outside. The brake pad state estimation device (100) variably sets a processing frequency (FP) of at least one of the brake pad state calculation process and the information output process. The processing frequency (FP) when a vehicle speed (V) is lower is lower than the processing frequency (FP) when the vehicle speed (V) is higher, or the processing frequency (FP) when a brake pressure (Pb) is lower is lower than the processing frequency (FP) when the brake pressure (Pb) is higher.
