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