PROBLEM TO BE SOLVED: To propose a sunlight collecting device shielding sunlight streaming into a room through a clearance between strip plates and allowing the longest possible time to irradiate the indoor ceiling with substantially the entire reflected light of the sunlight reflected by a mirror surface of the strip plate. SOLUTION: A plurality of strip plates 12 extending in the right-left direction of a window of a house into which the sunlight streams, with the upper face side formed as the mirror surface which reflects the sunlight and with the lower face side formed as a non-reflecting surface, are laminated through prescribed spaces in a vertical direction. Each strip plate 12 is rotatably provided, and a light shielding part 16b for shielding the sunlight streaming into the room through the clearance P when the incident angle of the sunlight to the horizontal plane is minimum within the time of collecting the sunlight, is provided inclining at each indoor side end part of the strip plate 12.
