The honeycomb panel 4 ′ having a blinding function whose side is hard to see can be easily obtained. The honeycomb panel 4 ′ is suitable, for example, as shown in FIGS. 3 and 4, by attaching it to the ventilation opening 6 of the door panel 5 so that the door panel 5 has a ventilation function as well as a blinding function.

Further, as shown in FIG. 5, if a sound absorbing material 7 such as glass wool or rock wool is attached to the back surface of the honeycomb panel 4, the honeycomb panel 4 passes through the many cylindrical hollow portions 2 from the front surface side. As a result, the sound absorbing panel can be effectively sound-absorbed by the sound-absorbing material 7 on the back side. In this case, the size of the tubular hollow portion 2 may be changed by changing the size of the uneven portion of the wooden corrugated board 1, or the same sound absorption material 7 on the honeycomb panel 4 or the back side.
The sound absorption characteristics can be adjusted and adjusted by changing the thickness dimension of the.
