PROBLEM TO BE SOLVED: To suppress temperature variation of a power charge element in which an end portion at one end side thereof is held by a holding member.SOLUTION: A power charge module has plural power charge elements arranged within a plane perpendicular to a predetermined direction so as to extend in the predetermined direction, a holder for holding one end portion of each of the plural power charge elements, and a case for accommodating the plural power charge elements. The case extends in the predetermined direction and has an air-intake port and an exhaust port of a heat-exchange medium which is in contact with areas of the power charge elements which are not held by the holder. The air-intake port is formed so that the aperture area of a portion thereof near to the holder is larger than that of a portion thereof far from the holder in the predetermined direction, and the exhaust port is formed so that the aperture area of a portion thereof near to the holder is smaller than that of a portion thereof far away from the holder in the predetermined direction. |
