A room temperature bonding apparatus includes: an angle adjustment mechanism that supports a first sample stage holding a first substrate to a first stage so as to be able to change a direction of the first sample stage; a first driving device that drives the first stage in a first direction; a second driving device that drives a second sample stage holding a second substrate in a second direction not parallel to the first direction; and a carriage support table that supports the second sample stage in the first direction when the second substrate and the first substrate are brought into press contact with each other. In this case, the room temperature bonding apparatus can impose a larger load exceeding a withstand load of the second driving device on the first substrate and the second substrate. Further, the room temperature bonding apparatus can use the angle adjustment mechanism to change a direction of the first substrate such that the first substrate and the second substrate come into parallel contact with each other, and uniformly impose the larger load on a bonding surface.
