A microchamber comprising a glass substrate ( 101 ) which is transparent to a specific wavelength, an absorbent region ( 102 ) which absorbs the specific wavelength, and a melting substance region ( 103 ) which does not absorb the specific wavelength, is solid at room temperature and melts when heated, which regions are layered on the glass substrate. The absorbent region, is irradiated with a focused light beam ( 402 ) of the specific wavelength and locally heated in the vicinity of the converging rays, so that the melting substance region ( 103 ) is locally melted at a portion adjacent to the absorbent region, thereby forming a cavity ( 403 ) as the focused light beam moves. Accordingly, the shape of the microchamber can be arbitrarily changed in accordance with the process of cell culture.
