The purpose of the present invention is to inexpensively provide an oxide sintered body which is formed of a niobium oxide and which has high strength, and to provide a production method with which the oxide sintered body can be easily obtained, without employing an HP method, by use of inexpensive equipment. According to the present invention, a compact undergoes firing at a temperature elevation rate of not lower than 400ºC/hour. L'objectif de la présente invention est de fournir de façon économique un corps fritté d'oxyde qui est formé d'un oxyde de niobium et qui présente une résistance élevée, et de fournir un procédé de production avec lequel le corps fritté d'oxyde peut être aisément obtenu, sans utiliser un procédé HP, au moyen d'un équipement peu coûteux. Selon la présente invention, une briquette subit une cuisson à un taux d'élévation de température d'au moins 400 °C/heure. 本発明の目的は、酸化ニオブからなる高強度な酸化物焼結体を安価に提供することであり、ＨＰ法によらず安価な設備で容易に得ることができる製造方法を提供することである。　成形体を４００℃／時間以上の昇温速度で焼成する。
