An action probability estimation device includes a risk calculation unit that calculates a risk index value as a numerical value representing a degree of magnitude of a collision risk between a traffic participant around a target vehicle and the target vehicle; and a probability estimation unit that estimates, on the basis of the risk index value and a driver characteristic as a characteristic of a driver of the target vehicle, an action probability that the driver executes a predetermined steering action, which is determined in advance, in the target vehicle, in which the driver characteristic includes a confidence level as a numerical value representing a degree of a level of confidence of the driver regarding his/her driving skill, and a situational daring level as a numerical value indicating a degree of magnitude of a tendency of the driver to carry out an action while knowing that it is dangerous.
