To inhibit a mold from being unevenly heated.SOLUTION: A heater for heating a mold 2 having a recess 2c and salients 2a, 2b on a top surface thereof comprises: a pedestal 11 on which the mold 2 is placed so that the mold 2's undersurface is in contact, the pedestal including a pedestal body 11a inside which an induction coil 11b is provided; and a ferrite 12 disposed between the induction coil 11b and the recess 2c of the mold 2. Thereby, a magnetic field from the induction coil in the vicinity of the recess of the mold is intercepted, enabling suppression of heating the recess of the mold.SELECTED DRAWING: Figure 3 【課題】型に対する不均等な加熱を抑制する。【解決手段】上面に凹部２ｃと凸部２ａ，２ｂとを有する型２を加熱する加熱装置であって、型２の下面が当接するように型２が載置されるとともに、台座本体１１ａの内部に誘導コイル１１ｂが設けられている台座１１と、誘導コイル１１ｂと型２の凹部２ｃとの間に配置されるフェライト１２と、を備える。これにより、型の凹部付近における誘導コイルからの磁界を遮断し、型の凹部の加熱を抑制することができる。【選択図】図３
