PROBLEM TO BE SOLVED: To provide an attitude determination apparatus capable of determining a self-attitude even in the case of being carried by a pedestrian and to provide a movement direction determination apparatus, a position determination apparatus, a computer program, and an attitude determination method. SOLUTION: A coordinate transformation part 31 performs coordinate transformation between apparatus orthogonal three-dimensional coordinates (X, Y, Z) and reference orthogonal three-dimensional coordinates (x, y, z) with a pitch angleα, a roll angleβ, and a yaw angleγas parameters. An angle computation part 32 computes the pitch angleα, the roll angleβ, and the yaw angleγby applying data (acceleration and geomagnetism) detected by a three-axis acceleration sensor 22 and a three-axis geomagnetic sensor 23 to coordinate transformation at the coordinate transformation part 31. An attitude determination part 30 determines the self-attitude by determining a pitch angleα, a roll angleβ, and a yaw angleγto the reference orthogonal three-dimensional coordinates (x, y, z) to be references.
