The present invention provides a multilayer body for a medical container which has excellent heat resistance due to an inner-most layer composed of cyclic polyolefin being strongly adhered to other layers without using an adhesive, and suitable anti-blocking properties in the case of being used as a film. In addition, the present invention provides a medical container which is composed of the multilayer body and has little deterioration of properties such as transparency and peeling strength even if it is subjected to a sterilization treatment by high pressure steam or the like.本發明係提供:即使不使用接著劑,由環狀聚烯烴所形成的內層,可與其他層良好地接著,耐熱性也優異,在為薄膜之情形時,耐阻隔性也良好的醫療容器用多層體;及由此醫療容器用多層體所形成,即使以高壓蒸汽來滅菌,透明性或剝離強度等之特性劣化少的醫療容器。10‧‧‧多層體11‧‧‧最內層12‧‧‧中間層13‧‧‧最外層
