NOVELTY - The fixing component has a clamp component (20) that is provided with fitting portion extended horizontal in upper end portion of axial component extended so as to be perpendicular than a base component (10) and an axial component. A frame (31) is equipped with fitting portion (21-23) and fitting recess to fit on opposite side to the panel insertion portion (33a,33b) by which a solar cell panel (32a,32b) is inserted and supported. The fitting portion is provided to hold fitting recess of frame.    USE - Fixing component of solar cell module installed in roof.    ADVANTAGE - The fitting portion of the frame and clamp component can be existed in the high position directly under a panel. The installation of the fixing component of solar cell module can be performed smoothly. The occurrences of damage and degradation to the roof can be prevented. Reliability of the fixing component of the solar power generation module attached to the housing roof can be improved. The attachment and the removal process of the solar cell module can be performed efficiently. The structure of the fixing component can be simplified. The maintenance operation of the solar cell module installed in the roof can be performed efficiently. The fixation strength with respect to the fixing component of the frame can be improved reliably. The motion to the up-down direction of the frame can be suppressed. The installation area of the solar cell module can be reduced. External appearance of the solar cell module can be enhanced.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a fixation structure of the solar cell module;    (2) the fixing method of the solar cell module; and    (3) the maintenance method of the solar cell module.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of the fixation structure of the solar cell module.    Base component (10)    Clamp component (20)    Fitting portions (21-23)    Frame (31)    Solar cell panel (32a,32b)    Panel insertion portions (33a,33b)
