To provide a catalyst-compounded formed body with which powdering and collapsing of the formed body is highly efficiently prevented at the time of packing it in a reactor and adhesive of the catalyst itself is made no need to be taken into consideration during the production process and which has excellent operability and industrial advantages.

The production method for the catalyst-compounded formed body comprises the steps of blocking a formed catalyst or a deposited catalyst by bonding the catalyst itself using a thermally decomposable polymer compound in a size sufficient to pack the catalyst blocks in a reactor. In the production method, the formed catalyst or the deposited catalyst is packed in a divided structure type bonding container made of a plastic and having an inner shape made at least partially similar to the inner shape of the reactor and an inner surface made of fluororesin or silicone resin and bonding the catalyst to itself using the thermally decomposable polymer compound.
