To provide a compact and highly efficient heating apparatus for continuously executing high-speed press forming of a steel plate for hot press forming.

The heating apparatus 210 of a steel plate for hot press forming includes a heating mechanism B for heating the steel plate 3, and a soaking mechanism C for soaking and keeping the heated steel plate 3 for a fixed time. The heating mechanism B has a plurality of batch-type heating devices 101-106 which receive one steel plate or one set of steel plates from a destack 20, and store the steel plate 3. The batch-type heating devices 101-106 heat the steel plate 3 while moving to the soaking mechanism C side. The soaking mechanism C receives the plurality of steel plates 3 from the batch-type heating devices 101-106, and continuously soaks the steel plates while conveying the steel plates 3. Thereafter, the steel plates 3 are delivered to a hot press apparatus 60.
