An electronic clinical thermometer includes a liquid crystal display element for displaying the result of a temperature measurement, and a lamp circuit for illuminating the liquid crystal display element automatically at the end of the temperature measurement only when a sensed amount of ambient light is insufficient to permit easy reading of the temperature displayed by the liquid crystal element. The lamp circuit is switched on and off electronically, eliminating the need for mechanical contacts and manually operated push-buttons, thus making it possible to obtain a liquid-tight structure.

An illuminating apparatus is provided and includes a plurality of point light sources in one plane and a first optical sheet and a second optical sheet overlapped in a region facing the plurality of point light sources. The plurality of point light sources are arranged in a first direction and also arranged in a second direction orthogonal to the first direction. The first optical sheet has a plurality of first three-dimensional structures extending in a direction parallel to the first direction and arranged in a direction parallel to the second direction. The second optical sheet has a plurality of second three-dimensional structures extending in a direction parallel to the second direction and arranged in a direction parallel to the first direction. Each of the second three-dimensional structures has a shape which generates a larger amount of return light from normal incident light as compared with the first three-dimensional structures.

Disclosed is an electronic clinical thermometer at least the temperature sensing portion of which, or the entire thermometer, has a flexible structure which adapts itself to any part of a body surface for automatically measuring body temperature or body surface temperature over an extended period of time. Preferably, the thermometer includes a power supply battery and a temperature measuring and storing circuit for storing in memory temperature data obtained by sensing temperature at a predetermined period by means of a temperature-responsive portion, reading out the temperature data stored in the memory in response to an externally applied data-read request, and outputting the temperature data to an external unit from a prescribed signal extracting portion. These elements are mounted on a flexible circuit board. The entirety of the electronic clinical thermometer, with the exception of the temperature-responsive portion and the signal extracting portion, is sealed and covered by a flexible, heat-insulative covering member.
