The present invention relates to a water proof case for a digital camera. The water proof case for a digital camera according to the present invention comprises a housing having an inner space to accommodate the digital camera, an upper and a lower transparent films formed, respectively, on an upper and a lower sides of the housing, a first attaching member formed on an upper surface of the housing at a side of the upper transparent film, a corrugated header extended from the housing at a side of the first attaching member, a cover connected to the housing at the side of the first attaching member and positioned at a back of the corrugated header, a second attaching member formed on an upper surface of the cover, and a light tube unit heat-fused to the upper transparent film. The water proof case for a digital camera of the present invention accomplishes enhanced sealing firstly by successive folding of the corrugated header or clip attachment to the corrugated header and secondly by binding of the second attaching member formed on the cover to the first attaching member of the housing. Further, the water proof case provides high quality image and can be prepared in a cost effective manner.
