To provide entertaining portable electronic equipment and a computer program.

A portable telephone 1 detects the temperature of the external atmosphere with a detection means (S101). It is determined whether or not the magnitude relationship between the detected temperature and a threshold is in prescribed relationship by comparing the detected temperature with the threshold recorded in a recording means (S102). When determined that the magnitude relationship between the detected temperature and the threshold is in the prescribed relationship (S102: YES), sound based on sound data recorded in the recording means is outputted from a sound output means (S103). Data communication are executed for accessing to a file or a program recorded in a device on a packet switching network on the basis of instruction information recorded in the recording means (S104). The data acquired by the executed data communication are displayed on a display means as a Web page with the processing by a browser (S105).
