Summary:To provide a heater with excellent durability.SOLUTION: A heater 1 comprises: a ceramic body 10; a heat element 20; a lead-out conductor 30; a through conductor 40; and an electrode pad 50. The ceramic body 10 is a rod-like member and includes a core part and an outer peripheral part covering a surface of the core part. The heat element 20 is embedded in the ceramic body 10 and extends from an end 14 to an end 15 of the ceramic body 10. The ceramic body 10 has convex portions that cover the heat element 20 and project outward and concave portions that are recessed inward compared with the convex portions.SELECTED DRAWING: Figure 1 【課題】耐久性に優れたヒータを提供する。【解決手段】ヒータ１は、セラミック体１０と、発熱抵抗体２０と、引出導体３０と、貫通導体４０と、電極パット５０を備える。セラミック体１０は、棒状の部材であり、芯部と芯部の表面を覆う外周部を含む。発熱抵抗体２０は、セラミック体１０に埋設され、セラミック体１０の端部１４から端部１５に向かって延びている。セラミック体１０は、発熱抵抗体２０を覆って外方に突出する凸部分と、凸部分より内方に窪んだ凹部分と、を有している。【選択図】図１
