A collision detection device applied to a vehicle having a hood lock at a vehicle front end center portion includes a first acceleration sensor, a second acceleration sensor, a hood opening and closing sensor, and one or more processors that determine that a front collision has occurred when a condition that first acceleration is higher than a first collision determination threshold value and second acceleration is higher than a second collision determination threshold value is satisfied. The one or more processors execute a threshold raising process of changing the first collision determination threshold value from the basic value to a correction value larger than the basic value in response to detection that the front hood is opened, and a process of returning the first collision determination threshold value to the basic value in response to elapse of a predetermined time from detection that the front hood is closed.
