PROBLEM TO BE SOLVED: To provide a heater having a simple configuration which can be easily manufactured and have little possibility of being broken, while achieving high warming efficiency and low production cost, and maintaining warm temperature safely even when the heater is in contact with a users body or a surrounding object.SOLUTION: A heater includes: a heat storing body 10 on which a plurality of air through holes 12 is formed a funnel-shaped electric bulb through hole 20 whose diameter gradually decreases towards a center of the heat storing body 10 an electric bulb 40 to which a power source and a socket 32 connected thereto are provided, and to which electric power is supplied by the power source from outside through the through hole 20, thereby emitting light and heat and a connection cord 50 having one end thereof connected to the heat storing body 10 and the other end connected to either a bedding tool or a mattress so as to prevent the heat storing body 10 from being detached, in which air flows through a first air flow hole 12 into and out of the heat storing body 10 so as to allow a circulation of warm air in the heat storing body 10 and to prevent a life of a filament of the electric bulb from being shortened.COPYRIGHT: (C)2015,JPO&INPIT【課題】低コストで高い保温効率を出すことができ、身体に触れたり物に触れても安全に保温を維持でき、構成が単純で、簡単に製作が可能で、故障する恐れがほとんどない保温器を提供する。【解決手段】複数の第1空気流通孔12が形成される蓄熱式本体10と、蓄熱式本体10の内部側に向かって徐々に直径が小さくなるように形成される漏斗形状の電球出入り部20と、外部から供給される電源と接続されるソケット32が備えられ、出入り部20を通じて電源の供給を受け、光と熱を発散する電球40と、一側は蓄熱式本体10に接続され、他側は寝具またはマットレスのいずれかに接続されて蓄熱式本体の離脱を防止する接続紐50とを含み、第1空気流通孔12を介して空気が蓄熱式本体10の内外部に流通されて蓄熱式本体10の温気の伝達と電球40のフィラメントの寿命短縮を防止する。【選択図】図1
