PROBLEM TO BE SOLVED: To provide a production system of propylene oxide having excellent features which are capable to produce propylene oxide stably so as to realize high reaction rate, so that the propylene oxide is produced by reacting propylene with cumene hydroperoxide in the presence of a solid catalyst. SOLUTION: The production system of propylene oxide involves the following steps. Step 1: Step for detecting reaction temperature (T). Step 2: Step for detecting reaction pressure (P). Step 3: Step for calculating Ps which is defined by the following formula (1). Step 4: Step for adjusting P so as to be satisfied the following formula (2). Ps =0.00007 T<2> +0.004 T (1). P>=Ps (2). Provided that, the units of P and Ps are [MPa guage], and the unit of T is [ deg.C], and 10<=T<=300.
